There are about 20 new " ICO managers/Teams" popping up weekly. I'm not saying the forum should "screen" all of them per say, but maybe some Merit restrictions and rank restrictions should be put into place before anyone can offer managing services?

I don't think think it's out of the question to require teams to use a forum escrow or must hire a manager from an approved list.(There is no actual list unless you count https://bitcointalk.org/index.php?topic=5032713.0 https://bitcointalk.org/index.php?topic=4412712.0 these) An official list could be made but then the forum is basically endorsing the users put on the list, or the forum could ask a disclaimer to be added to any list be made by the community.

Users that have shown interest in the quality of their posts and posting habits IMO are more likely to actually care about the campaigns they manage. More likely to care about spam.

I also like the suggestion of no token paying signature campaigns allowed. Maybe also include translations as well. I think facebook, twitter, youtube, instragram, reddit, blogs etc are fine as they are not spamming the forum. Just my opinion
