I was googling some random stuff trying to help you out with this OP but unfortunately it seems that you are not presenting the truth here.
In your screenshot above you show your name on chips being "PozerDispozr24"[1] and I found an interesting forum profile of someone named "PoserDispozr4"[2] playing on stake.com and sharing some big wins on this forum, one "adamncn24"[2.1] which just happens to be, by your own admission, a name that you have used. It just seems to be too many coincidences for this to line up in your favor, unfortunately.
Here's a snippet from one such post from that forum profile:
"My name is Adam, I am an old school gambler and have played on most sites considered to be ok that accepts US players. I can't wait until the legality of online gambling spreads from being legal only in a handful of US states to being legal in most states in our country. I feel that only then we will catch a truly fair shake when gambling online."[2.2]
It seems to me that the odds are stacked against you in trying to prove something here which you know just isn't true and I can understand this from Chips.gg's POV. It looks like you knew exactly what you were doing was not allowed in accordance with the ToS to the extent that when you eventually hit big (even after making a larger withdraw prior), you went on to have someone else submit documents and claim that they belonged to you while in fact you have a seemingly large digital fingerprint so that anyone can see that you are more likely than not from USA.
I'm pretty confident in saying that if you would have just come clean to Chips when you hit some big wins and told them "Hey guys, it's pretty fucked up what's going on but I'm actually playing from the US which is against your ToS but maybe we could come to some agreement regarding this money here and then you close my account and I agree to not play here again". < This may have not had any effect and they could have, rightfully so, closed your account regardless but it would have been better than just instantly turning to lies to the extent that you submit someone else's documents as your own.. It's nefarious and malicious and even now you are making all of this noise with a post here on bitcointalk and calling out other users here who doubt your story.
