Searching for the bitcoin address in twitter gives an absolute ton of results. Are all these accounts hacked, or are people now posting just to joke around?
Then they'll just start obscuring addresses by interspersing them with spaces or posting links to third-party sites containing the address.
It's an unending game of cat and mouse. IMO Twitter's efforts at this point are much better spent on finding out how the hack occurred and cutting it off at the source.
