Report the Scam
It's essential to tag every scam address so that transactions with it can be detected and avoided. There are no bitcoin police. The community has to step up.

Report Stolen Bitcoin
You can report stolen bitcoin to the FBI but they're not going to do anything unless it's a million dollar scam. By immediately reporting to BitcoinWhosWho, legitimate downstream actors will know when an incoming transaction is tainted and be in a position to act.
