So I've given Party a week now to respond. They didn't even bother to reply with a "thanks, we've received your email".
Instead, someone from Party (the OP), decided to post my findings on 2+2 or leak them to someone to post. I believe the OP to be someone from Party's security team based in India but I don't have any proof of that.
So to clarify, almost all the info in the OP (excluding some of his own "findings" like the PTR comments lol) is researched by me which I then emailed to Party last week on tuesday or wednesday. It also included about 50 hand histories to show the very similar lines and exact same betsizes they both use.
The OP also included their screen names which I'll out now as originally I wanted to give Party some time to investigate before outing them (so I asked a mod to edit them out) but seeing the accounts are still playing and nothing had happened, hopefully outing them will speed things up (whatever direction this takes).
I'll include the stats here from PTR (thanks to 2+2er Any2cards2008 who originally noticed their similar playing styles and stats from PTR) and I'm gonna post the hand histories later after I've converted them to 2+2 format.
The suspected bot accounts are "jackaroo" and "BluDevill". Both big winners at Party ssnl over a huge sample.
