By damaging the people that spam to fill up their number of weekly posts for the signature campaign you also damage those who provide value and leverage their post count by using a signature. The signature has multiple use cases. ALTHOUGH is mostly used for bounties, that's not its only use case and definitely not the most rewarded.

There's a lot of people that own personal blogs and strive to create a community and generate traffic by posting useful content on this forum. Post count is merely a number that has no value unless each provides at least a bit of useful information.

Perhaps, if some filters would be implemented for any ICO that wants to post their announcement on this forum in order to lessen the number of scams, then the forum would probably be more clean and less spammy.

Nonetheless, eliminating the signature is not a balanced change and would affect other people, there should be a way, a change, that would only punish the spammers -Not everybody that uses a forum signature.
