What we should do is either 1) go to clips4sale and tell them he is selling pirated material that isn't authentic to him, or 2) go to his site, see who he has fighting in the videos he has posted, and search for those people... so they can in turn sue him for defamation of character.
Well the reason for his asking for clips of a person fighting is more an educated guess since in the past he has ::
1. used clips and pictures from his company and claimed they are of "his girlfriend" to chat people up
2. used pictures of his fighters holding verification signs to make the female profiles he creates look legit
3. Posted links to his company 24 times in a month on the forum, while claiming he had no affiliation with them
4. posted pirated links to his competition's videos claiming he was "'reporting it" yes if only we had some sort of private message he could have used instead..
So yeah given how odd it is to want to trade clips of each other fighting to verify ID, I wouldn't be shocked if some scummy purpose was at work.
Although it would be justice if someone else traded another producer's clip with the copyright edited off and his dumb ass posted it as his own for sale and that is what sinks him
