Stopping the report spam would be a good start.

I don't think people use bots to do whole bounty process, but this is what I see a lot:

1: newbie with 1 post joins a certain bounty
2: next post: another newbie with 1 post joins
3: next post: another newbie with 1 post joins

Can't help thinking that must be one person .... They probably have social accounts with inflated followers. Bounty managers get more work getting those accounts off the bounties. More useless work for everybody. If they manage to get unnoticed, they get more stakes from the bounty.

Then later on, the newbie account only go up in rank due to the reports in the bounty section, they never post on other sections of the forum.

I'm a bountyhunter myself, I would love to stop reporting my work on the forum, but I have to report.
I love the bounties that use forms for that, a better way to report your work.

My two cents.
