As it stands, we are at a fine balance on allowing signature campaigns and controlling spam on the forum and if we're to swing ay way, I'll suggest we go towards more regulation for spam and this is a community exercise, meaning if you report posts that are off topic or redundant, it will help the mods to find and delete them.

I personally think the forum is better off with signatures, sure it is an incentive to post and some of those posts might be forced or repetitive, but a huge chunk of them are educative and helpful. Most of what I have learnt from the forum were from users who were wearing signatures. Removing signatures will also cut down on educative posts as well as spam replies.
