I love the responses basically saying:
"he's not a thief, he just took money from people for something he couldn't produce and now won't refund it"
That, my friends, is a thief. It's too bad he's "depressed" or "suffers from depression" or whatever, but that's not an excuse to steal other people's hard earned money.
I feel bad for you guys, and hope somehow, someone starts legal action against him.
Some people simply have no respect for others, and he sounds like one of them.
