The Stop Forum Spam plugin can help weed out human spammers who are able to bypass Discourse’s built-in spam tools (thanks to their awesome human powers). Right after a new user signs up on your forum (before they have time to post), this plugin will check the user's email address, forum username, and/or IP address (depending on your plugin settings) against the Stop Forum Spam database. If the user is found in this database of known spammers, their user account will be immediately auto silenced in Discourse.
Note: If needed, you can unsilence the user in the Users → Silenced section of the Discourse Admin.
Follow these instructions to install this plugin in your Discourse installation.
Note: This plugin's git clone url is https://github.com/singerscreations/discourse-stopforumspam.git.
After installing this plugin in Discourse, you'll be able to configure the following settings in the Settings → Plugins section of the Discourse Admin:
-
stopforumspam enabled: Enable the Stop Forum Spam plugin. This will auto silence new users who are in the Stop Forum Spam database of known spammers.
-
stopforumspam check email: Silence new user if email is found in Stop Forum Spam database.
-
stopforumspam check username: Silence new user if username is found in Stop Forum Spam database.
-
stopforumspam check ip: Silence new user if IP is found in Stop Forum Spam database.
-
stopforumspam minimum entries found: User must appear in the Stop Forum Spam database at least this number of times.
-
stopforumspam recheck users after hours: Number of hours to wait before rechecking new users a second time to make sure they are still not in the Stop Forum Spam database. Set to 0 to disable recheck.
Note: If you have more than one of these check settings enabled, the user will be deemed a spammer as soon as one of them is found in the Stop Forum Spam database.
