I've gotten a lot more strict as time passes in moderating my sections, although I must admit the bounty section in particular is a completely different kettle of fish. I'm basically trying to go through the entire section of the ones I moderate, and effectively try, and remove the backlog of spam we've had over the years. Unfortunately, I'm not sure that's even possible with the bounty section since bounty sections aren't really all that effected by the bumping changes theymos introduced, which actually did impact the announcement sections quite some bit. So, there's a ton more work to be done in that section.
I don't know the answer to how we can effectively sort that section out. You could probably put ten moderators in there, and they wouldn't be able to sort out all the spam.
There was a suggestion I wanted to bring up but I saw no need to bring it up for people to discuss about it. I have noticed some people are just having alts, create new accounts, spam or having scam attempt, their account can be banned or their attempt scam thread is deleted, later you will see same thing again repeatedly. I was thinking why this forum do not make email mandatory because it will reduce this.
But I later realized that this forum is still good and better after email is not included, the IP evil fee and report to moderator is working and this forum is getting better with that.
The thing is with email verification it's easily bypassed. I mean, these users are doing the captcha's required to register/login so they don't mind creating a temporary email. If you're suggesting that we disallow temporary emails, that's a potential privacy concern, which effectively punishes the legitimate users, as well as those that might be malicious. Therefore, I don't think that's the best approach to this.
