I should mention that they have contacted me as well – and I pissed them off by purchasing a couple of the names on my own via Godaddy 
I told them that Casinomeister is trademarked and protected by international treaties – anyone picking up a Casinomeister domain is pretty much obligated to hand it over to me.
He called me “unprofessional” and “unethical” – I told him to stick it up his ass.
When I get a spare moment, I’ll be reporting them to ICANN.
Word of advice, Gamtrak – if you haven’t already, apply for a trademark to protect yourself from unscrupulous opportunists:
