Alright, whatever.
I'm sure that I can't explain the exact situation to you. It doesn't really matter anyway. The fact is that I will not offer support to people who steal the software. Who's to say they won't steal something I write next. If I get the impression that they don't have a legal copy, I will question them and if things continue to be suspicious, will just tell them "I don't know".
