So nobody liked my idea that bad campaigns should be banned, rather than a complete block on signatures ( which would kill the forum ).
It's a good idea but how do you do it. You can ban the signature campaign managers from the forum but there's nothing to stop them organising a campaign off-forum. You should tell that friend of yours to register btctalksigcamp.com ASAP.
Poorly run campaigns were meant to have their signatures blacklisted/blocked from the forum by theymos to stop this from happening. Several poorly run campaigns were suggested but it never happened.
