Interesting. That's a lot of evidence against op and I feel like your team did the right thing here since he clearly took advantage of fixed matches in a pretty transparent manner and expected to get away since your site is a betting exchange.
thats why i asked if the above mentioned bets on potential match fixing games were actually matched on/by Pinnacle.
They probably were matched by Pinnacle since they aren't immune to fixed matches or anything though I am curious as to why you are concerned about this link.
