How to stop forum spam in MyBB Forums

Spam Prevention and Security MyBB

Forum Spam are the reason why 30% of the forums die. The reason being genuine members of a forum gets spammed by private messagesor forum posts or forum threads causing members to create a negative impression about the forum which results in decline in their activity.

We were asked by our clients to recommend an antispam solution to stop forum spam. Preventing forum spam is not easy because these days there are two type of spammers. First is bots and second is human spammers who wants to get traffic by cheap methods. So to stop forum spam we need tools as well as educated moderators who can create a healthy community and get rid of spams. There are some MyBB Spam Prevention methods and plugins that i will suggest every forum administrator to use are

1. Stop Forum Spam

Stop Forum spam is a website with database of all the big spammers who have been identified for spamming and are currently spamming. The best part of Stop Forum spam is it is already present in MyBB and added as a default feature in the core. You just to enable in General Settings and that’s it.


Second plugin that i will suggest will be Spamalyser, although this plugin needs to be configured accurately but when done it checks the post on basis of weight and this helps you to do various action on basis of spam weight. Spamalyser is a plugin for MyBB 1.6 series and is not required for 1.8 series.

3. Recaptcha in place of MyBB Default Captcha

Use of Recaptcha is better because it is tougher than Default Captcha to solve. It is available under MyBB General Settings and you can get public and private keys here

4. Registration Security Questions

Registration Security question used to be one of the highest downloaded MyBB plugin and can be helpful to stop human based spammers. No wonder it is most downloaded plugin because of this reason and now in MyBB 1.8, it is a default feature in the core, you just need to enable and add your own questions in General Settings.

5.  MyBB group Promotions

Use MyBB group promotion to remove various posting permission untill the spammer have completed a day or say. This is very useful method to reduce forum spam

6. Remove signature Permissions

Do not allow members to post signature links in profile and signature until they have reached a certain amount of posts, this can help is stopping forum spam because lots of spammer register to do this only.
