That's precisely the problem: we haven't heard from him since the time he posted about his hack.
If raocow is going to play games Matt worked on he should first ask him about this, not out of ill will but to see if he has something to share about this. I would not want to see him come to brag about his game a couple times and leave without answering anything again.
Does he still have those forums and has someone tried asking about it?
