List of Spam Prevention Plugins

[Paul H.]

Here is a list some of the best anti-spam plugins for MyBB.


Prevent Spammers From Registering

Register Time

• This plugin is made to block spambots such as XRumer from registering on your board. Spambots generally finish the registration form within five seconds, or even less. A human cannot possibly complete the form in that time. This plugin measures the time between when the form is loaded and when the form is submitted. If the time is less than the setting in the ACP (by default 15 seconds) an error is thrown and registration does not take place.

• "This plugin is aimed to help combat the ever present war on spam, this enables you to check all new registrations to your forum against the stopforumspam.com database to see if they are known spammers. It can check their username, email and IP address."

• "The plug in will block known spammers/bots from registering via IP, email address, anonymous proxy, top email domains, top ISP - (Internet Service Provider) spammers. Also, allows you to block countries via country code and region's."

• This plugin "simply hide signatures and website links of users with low post counts. Adds a setting under Profile options to specify the minimum post count for signatures to be shown. It will hide signatures in posts and the profile page, and will give a warning in the edit signature page that signatures will be hidden."

• In short, Spamalyser tries to detect spam posts (not spam registrations) through a number of means and can perform some actions on detected spam.

http://mods.mybb.com/view/auto-website-r...in-profile

• This plugin stops users joining your forums in order to just leave an link to there website in there profile they have to get an set amount off posts first before they can even think about adding an link in there profile. made this plugin after getting an lot off bots joining my site in order two do this so i thought i would make this plugin and share it with the rest off you.

http://mods.mybb.com/view/bad-behavior

• Bad Behavior is a PHP-based solution for blocking link spam and the robots which deliver it. Bad Behavior complements other link spam solutions by acting as a gatekeeper, preventing spammers from ever delivering their junk, and in many cases, from ever reading your site in the first place. This keeps your site's load down, makes your site logs cleaner, and can help prevent denial of service conditions caused by spammers.

If you know a plugin that you think should be added to the list, send me a PM and I'll add it.

Why no love for Spamalyser? I use it and find it to help rather a lot.

Also, you should mention Solidus' post regarding CSF which shows how to implement spamhaus and other IP blocks against spammer.

I was a user of www.stopforumspam.com website for months to identify spammers before finding and installing the plugin. It absolutely works great! My forum would get almost 30 spam accounts a day and I'd have to shut down registration as part of cleanup. After installing this plugin I only had 1 spammer account created in 2 weeks and after checking stopforumspam.com deleted it before spam was posted.
