well, if you see the agreement in first post then there is a set amount of btc agreed upon, which he refuses to pay. 2nd, he chose to pay out a player from holland but put some basic bs in the email and since i know most of the players from holland on a better level than just site owner, I have enough grounds for legal action.
Besides that, the site will be done before they even started, when you show to scam people like this. I'm sure this thread will be brought up when they try to launch their site. Aside from that, I might not have the best reputation in this space, but plo8monster goes back years in bitcoin poker and knows most of y'all personally. Guess I don't even have to vouch for his integrity...
Almost done with finalizing the further legal steps. Will update you guys soon!
