Firstly, I think this thread should be in Meta [https://bitcointalk.org/index.php?board=24.0].

1. theymos, moderators, and co shouldn't guarantee the success of crypto investors. They must be smarter and more careful to avoid scam projects. Forum has already taken some actions to wipe out scams/scammers. There are many members that already did regular reports for scam cases. And give red-trust to all parties involved in that scams.  

2. We can see the reputation of each bounty manager. Simply choose bounty managers with green-trust accounts and avoid/ignore managers with red-trust accounts.
