I still can't see the "email" but assuming everything was their exact response



""with identical playing stats""
this is possible esp since they're basing it off only 3000 hands


""""we have no choice but to ban the accounts regardless of what may or may not be the case. We have very strict rules on this to preserve integrity. This is not the first or last time we will see such cases. Our reaction will always be the same. This will be our last response on this query."""

This is them admitting they may or may not have made the correct decision, and refusing to investigate it further with 16000$ on the line.
This is probably the only thing that matters

But this is still just me making assumptions, i can't verify they sent it or that if they did send it, it's exactly how they put it.

Aside from that, i see chazley made a post saying they're shady.
someone i respect and have a history with, pretty sure hes trusted by alot of people here too so that helps.

If you truly want to expose this site here's the proof i think you will need to provide.
1:A clear image of the email with the sender.

2:If you used a hud or have your hand history files those would help. they're accusing you of  similar play styles which isn't how reviewing for collusion works
You said a majority of those hands weren't played at the same tables, and collusion depends on if you played against each other or with "making folds/raises" that players wouldn't normally make otherwise.
It would help to see how many of those 3,000hands where played together, and a copy of both of your histories for those hands played together "so we could see both of your hole cards"

3: like the post on the other thread said "letters from ISP that confirms your story about the IP sharing" or activity logs to confirm that those ips where even showing the same or not and if the patterns matchup.
isp confirmation would be better then having the activity log, but if you're unable to get their cooperation i think there's a few different ways to get the activity log that could help you out.

4: leave this thread and create a scam accusation thread so the proof you provide won't be scattered in the 17pages here, and so others can share their proof that will further support your claims.
