Invision Community Spam Prevention

1. Spam Defence Service

The IC Spam Defence Service, a complimentary offering for active license holders, is your first line of defense. It evaluates each user’s registration likelihood of being spam on a scale from 1 to 4.

Setting Up Spam Defence:

• Configure actions taken when potential spammers are detected.

Options include:

• Allowing users to register normally.
• Allowing registration but requiring approval for all posts.
• Flagging the account for manual review.
• Registering the account but immediately banning it.
• Disallowing the user from registering altogether.

2. Logging

Effortlessly monitor the level assigned to registering members and review registration logs to address any registration issues promptly.

3. White Listing

In certain cases, a user may be flagged at a higher level than desired, such as during testing. To prevent registration hiccups, whitelist specific users or IP addresses to bypass the spam check.

4. CAPTCHA

CAPTCHA serves as your trusty guardian against automated spamming bots. Invision Community offers various CAPTCHA options under the ‘CAPTCHA’ tab in the spam prevention section, including:

• Invisible reCAPTCHA (background verification).
• reCAPTCHA V2 (checkbox verification).
• keyCAPTCHA (jigsaw puzzle completion).
• hCaptcha (checkbox and image selection).

Remember, you need to create a (free) API key for each selected service, accessible under the key section related to your chosen service.

Important Note: Google has discontinued reCAPTCHA v1; for Invision Community 4.2 or below, reset your CAPTCHA service preference to reCAPTCHA 2 or keyCAPTCHA.

5. Flagging Spammers

Customize actions when a member is flagged as a spammer, including automatic banning, content removal, and notification.

Flag spammers from three areas on the site:

• Member list in the admin CP.
• Member’s profile on the front end.
• ‘More Options’ menu in a member card.

6. Question and Answer Challenge

Add an extra layer of protection with customizable questions and answers to verify a user’s humanity. Craft questions that require thoughtful responses, making it challenging for bots to bypass.

Examples:

• Question: “What is the third letter of the 5th word in this sentence?” Answer: “t”
• Question: “What is the 3rd word in this sentence after the comma?” Answer: “sentence”

With this guide, you’re equipped to become a spam prevention virtuoso in Invision Community, ensuring a secure and enjoyable online community for your members.

XenForo Spam Prevention

To unleash the power of XenForo’s spam prevention arsenal, navigate to the Spam management options within your admin panel.

1. Registrations

XenForo offers several tools to thwart spam registrations, all conveniently located in the Spam management options:

• StopForumSpam Database: Tap into this collaborative database, utilized by countless forums, to identify and prevent known spammers from registering. Integration behavior can be tailored based on database result confidence. You can also contribute by submitting spam information to StopForumSpam when banning a spammer using the spam cleaner.
• DNS Block Lists: Employ DNS block lists, such as the Tornevall DNSBL, to verify a user’s IP against known spam IPs and take appropriate action.
• Registration Timer: Though a modest defense, setting a registration timer can thwart automated scripts by preventing rapid form submissions. However, be cautious not to set this value too high, as it may affect human users.

2. Content

Even if spammers bypass automated registration checks and successfully register, XenForo offers a second line of defense to prevent spam content. These options reside in the Spam management options:

• Spam Phrases: Define spam phrases, and if any of a user’s initial messages match these phrases, take action. For example, block messages with phrases like “watch film name online” by using a matching pattern like “watch * online.”
• Akismet Integration: Harness Akismet, a heuristic-based service that identifies spam content. When Akismet flags content as spam, it is placed in your forum’s moderation queue for manual approval or deletion before being displayed to regular visitors.

3. CAPTCHA

XenForo offers two CAPTCHA systems, each serving as a robust spam prevention mechanism. You can choose between these options under the ‘CAPTCHA’ tab in the spam prevention section:

• ReCAPTCHA: This system requires visitors to perform tasks that are challenging for machines to complete.
• Question & Answer CAPTCHA: Customize a set of questions and answers that users must correctly respond to during registration or when posting messages (if guest posting is allowed).

Configuring CAPTCHA:

• Access the CAPTCHA settings in the admin control panel.
• Choose your preferred CAPTCHA type under ‘Enable CAPTCHA for guests.’

4. The Spam Cleaner

XenForo introduces the Spam Cleaner, a powerful tool for efficiently handling spam in user-generated content. Accessible with just a few clicks, this tool empowers you to swiftly combat spam on your forum.

Configuring the Spam Cleaner:

• Access the Spam management group within the admin control panel.

Key configurations include:

• Defining criteria for making the Spam Cleaner available to members based on message count, elapsed days since registration, and received Likes.
• Customizing actions taken on affected threads and messages, including permanent deletion, removal from public view, and thread relocation.
• Modifying the default email text for communication when using the Spam Cleaner.
• Conducting IP checks to identify matches with other members over a specified time period.

Using the Spam Cleaner:

To utilize the Spam Cleaner, ensure users have the necessary spam cleaner permissions enabled, either through user groups or user permissions.

You can initiate the Spam Cleaner from various locations, including threads, profile posts, member popups, and profile pages. A Spam Cleaner overlay will appear, allowing you to select actions ranging from IP checks to permanent bans and content removal.

Restoring Deleted Content:

If you wish to restore content deleted by the Spam Cleaner, you can do so using the Restore option. Access the Spam cleaner log in the Tools section of the admin control panel, review deleted content, and selectively restore it as needed.

With this comprehensive guide, you’ll wield XenForo’s spam prevention arsenal like a pro, ensuring a spam-free and enjoyable environment for your online community.

vBulletin Spam Prevention

Accessing Anti-Spam Tools

To harness the power of vBulletin’s anti-spam arsenal, navigate to the Anti-Spam settings within your admin panel.

1. Anti-Spam Service (default: Disable Scanning)

The Anti-Spam Service is a vital component in spam prevention. You must select the corresponding service (Akismet or Typepad Anti-spam) and enter the API key provided by your chosen service to enable scanning of supported data.

2. vBulletin Anti-Spam Key

To activate user data scanning, obtain a vBulletin Anti-Spam service key from the service selected in the Anti-Spam Service option. Enter this key to enable scanning of user data where supported.

3. Spam Scanning Post Threshold (default: 0)

This setting determines how many of a user’s posts are scanned by the Anti-Spam Service. Once a user’s post count surpasses this threshold, their posts are no longer subjected to spam content scanning.

To ensure all posts are always scanned, set this value to 0.

4. Anti-Spam Data Storage Length (Days) (default: 7)

Every time a post is created, vBulletin stores additional anti-spam data. This data is invaluable for submitting information about false positives and false negatives to the chosen anti-spam system, contributing to its improvement.

This setting defines the duration (in days) for which this data is retained.

With this comprehensive guide, you’ll wield vBulletin’s anti-spam tools adeptly, maintaining a spam-free and user-friendly environment for your online community.

Woltlab Spam Prevention

1. Making Links ‘nofollow’ and ‘ugc’

Configure your forum to label links as ‘nofollow’ and ‘ugc.’ This signals search engines to ignore these links in forum posts, making SEO spam less appealing to spammers. WoltLab Suite sets this configuration as the default, emphasizing the importance of marking links from “user-generated content.”

2. Activate a Captcha in the Registration Form

Combat automated spam by implementing Captchas in your registration process. Try question-and-answer Captchas with carefully crafted questions to outsmart spam robots. Avoid overly simplistic questions that can be easily answered via search engines.

3. Utilize Stop Forum Spam

Employ the “Stop Forum Spam” project to deter spammers. This project aggregates spammer data in a central database, making it easier to identify and block suspicious registrations. WoltLab Suite offers seamless integration with this service, enhancing your spam-fighting efforts while adhering to GDPR requirements.

4. Confirm Email Addresses

Require users to confirm their email addresses after registration before allowing them to post content. Restrict their ability to edit profiles until email confirmation is complete.

5. Limit Editing Capabilities

Prevent spammers from subtly inserting spam into their posts over time by restricting the time window for post editing, especially for new users.

6. Manual Approval of New Users

For smaller communities, consider manually reviewing and approving new user registrations as an administrator. This hands-on approach ensures that only genuine users gain access.

7. Activate Flood Control

Enable flood control to limit the number of posts a user can make within a defined time frame. This is particularly effective for new users and prevents spam bursts.

8. Manual Review and Approval

In extreme cases, manually review and approve content from new users before it’s posted. Employ automatic group assignment to promote trusted users to groups that don’t require prior review.
