In the process of trying to uncover more details about the scammers deliciousowl (== gumcruise), we uncovered something a bit disturbing about the person he happened to pay 0.5 BTC to.
The first main post containing evidence:
Note 11/08/2015 should say 11/08/2013, but the evidence is pretty incriminating. However some people were not yet convinced, but Phinn brought up some more evidence that conclusively shows that BitcoinStriker is indeed Tymer: One piece of evidence where he calls himself Tymer, and more evidence where his address is used on the server MinecraftCC (run by the magnificent SgtSpike) under a username where he is clearly called Tymer. And another piece where he effectively calls himself Tymer. And some more.
Nothing more needs to be provided. The rep should stay forever so his account becomes defunct.
