We know most forum users have different goals to join this forum, there are only some users who are really interested in getting to know bitcoin technically while others are bounty hunters, traders, gamblers and spammers and other. If bounties and signature campaign are removed or banned, the user base will decline rapidly. I am very sure of that.
Whether or not that is a positive or negative thing is subjective. I'm sure there are users here hoping that the community rids of the spam issue that signature campaigns bring, and go back to a more tight knitted community, while others are probably hoping for more, and more active users so that there's more potential to earn.
