Wouldn't it be possible to block this attack by flagging all tweets containing the Bitcoin address in question? I would've assumed that Twitter could do something like this, maybe even already set up an automated system.
Treating the symptom and not the cause. The scam itself is (arguably) less damaging than whatever the hacker(s) can do with the access they've obtained.
Block bitcoin addresses, and they'll move on to different types of messages.
