xF1 Add-on Regex Moderation 1.3.1

This add-on can detect obscured spam in posts. There are two ACP options with which you can control the detection behavior:


1. Single characters words

With this option you can restrict how many single character words the message may contain at most. This is to prevent spammers that type for example „b a d w o r d“ instead of „badword“.



2. Word patterns

With this option you can state a regular expressions that will be applied to each word of the message. If one of the patterns matches at least once, the post will be moderated.



You can for example moderate all posts that contain at least one word with the format „b.a.d.w.o.r.d“ with this pattern:

[^\s]+\.[^\s]\.[^\s]*

Note: you can only use PCRE syntax.

You can analyse an test the saved word patterns on regex101.com by clicking on the corresponding link.

Note that the „word pattern“ you state is used to build the actual regex which is then applied to the whole message. That means „in the background“ each word pattern is prefixed with /[[:space:]]+ and postfixed with [[:space:]]+/. So for a word pattern abc the actual regex would be /[[:space:]]+abc[[:space:]]+/.


Bypassing moderation
The regex moderation will be disabled if the user has the permission to approve/unapprove posts or the permission to bypass regex moderation.
