I suggest that posts in the off topic section dont have signatures enabled, i think we will see less spammers there
i know they will move to other boards but it will be easier to see spam in the other boards
your thoughts?
If you want to get rid of spammer is contact who helding the signature campaign or his manager.
And about the rule , it should make for not posting on selected section, example for this case is off topic,
I'm sure that it will reduce some spam on this section
