As it stands, we are at a fine balance on allowing signature campaigns and controlling spam on the forum.
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.
That's true mate, the forum is very much field with reliable knowledge and most of it is fuel by the purpose of having signature campaigns especially when it comes to signature campaigns about CEX , DEX, and so many Bitcoin related software campaigns, I mean people tend to learn really educative stuffs from about these services and also their are some good boards and good people that still hold and contributive proactively here in the community and most of them are signature campaign promoted so signature campaigns is a plus to the community here.
