A much better suggestion would be to hold bounty campaigns and their managers responsible for the crap people are posting under their bounties. If they're accepting anyone without any quality controls and spamming and copy and pasting is rife then there should be some repercussions for that and until there is nothing will really change around here.
Force bounty managers to make a list with the usernames of the people they are accepting for the bounty.
Compare then the list with the members banned, once they reach x users the bounty manager gets also banned.
Most have spreadsheets that can be viewed. I think there should be some rule in place that if say 5 or 10 users on your campaign are banned for low quality posts or copy and pasting then your campaign also meets some punishments (thread deleted, accounts banned, signatures backlisted etc). This would soon make bounty managers and the people responsible clean up their campaigns. They only do nothing now because they don't need to as there's no repercussions at all for accepting anyone and paying for anything.
But back to serious and things that might be done...
Can we get rid of ALL CAPS titles?
But capslock means it's serious business and must be seen.
