XF 2.2 Spam regex not working

[dieg0]

Hi guys,

I'm getting a bunch of spam posts by new users. Some of these messages include links so I decided to give the spam regex admin.php?options/groups/spam/ a try so that users with less than X posts can't use links. With no success. At all.

The last thing I've tried is @Mike 's regex

^(?>(?i)(?!www|http|\.com|\.net|\.org|\.biz|\.ru).)*$

The URL I'm using for my test is

https://stackoverflow.com/questions/3809401/what-is-a-good-regular-expression-to-match-a-url

I've created a new user with 0 posts and I can post that stackoverflow link. Why is that?

Some of my previous tries were

https?:\/\/(www\.)?[-a-zA-Z0-9@:%._\+~#=]{2,256}\.[a-z]{2,4}\b([-a-zA-Z0-9@:%_\+.~#?&//=]*)

(http(s)?:\/\/.)?(www\.)?[-a-zA-Z0-9@:%._\+~#=]{2,256}\.[a-z]{2,6}\b([-a-zA-Z0-9@:%_\+.~#?&//=]*)

I'm currently running v2.2.7 Patch 1

This is the error log from the admin panel
