Help with regex for bots

[osiris]

Hi everyone,

I've had this flood of spambots on my network recently and I've been trying to write a regex that is going to kill them but not kill some other users.

Example bot nicks:

philipmM54
josieafF22
markasP07

etc

I want a regex that is going to kill nicknames that have a capital letter and 2 numbers in the last part of the nickname killed.

The regex I wrote is:
[A-Z]{1}[0-9]{2}!

And I've tried:
^[A-Z]{1}[0-9]{2}!

and also:
^\w+[A-Z]{1}[0-9]{2}!

All will kill the bots but also kill nicknames such as

snowman01
Scrawl07
Tunix21

Any ideas? I do not want to kill nicknames that end in 2 numbers but 1 capital AND 2 numbers.

By the way I am entering these by the /spamfilter command not by putting them in the .conf file

Any help is muchly appreciated!

The documentation clearly states that spamfiler are case insensitive.
If you want them to be case sensitive, you have to turn case insensitivity off with (?-i).

So you could try something like

Code: Select all

^[a-z]+(?-i:[A-Z])[0-9]{2}!
