Seems you have created newbie flag, and I think its appropriate. Supported from my side as well since it was clear ponzi scam attempt.
CatchaBTC violated bustabit's rights by pirating its software and arguably caused damages by not purchasing a software license instead. I'm unsure whether that's equivalent to violating an agreement, though, so I've supported your flag instead of adding a new one.
Marlboroza has been created newbie flag since he/she had not scammed directly or broke any written contract with him. You might create scam flag and it will show for all user. Perhaps you might need to create a thread how they broke contract with you or how they scam/cheat you.
