By further reviewing your account, we noticed a possible close relation with account: 5210473. For this reason, you are required to explain to us your relation with this user.
How the hell are you supposed to explain your relationship with another user, assuming it's
not an alt account? If you tell Nitrogensports that you have no idea what they're talking about, I doubt that'll satisfy them, and if there is some kind of relationship between you and Mr. 5210473, then it's also not going to end up well for you.
Are you using a VPN, by any chance? I've heard theories that if two people are connected to the same VPN server and have the same IP address (I don't know much about how that works or if it's possible), you can be flagged as being the same person on gambling sites. I believe I read a scam accusation recently where that was suspected.
I'm surprised no one has chimed in on this yet. Hopefully someone will, but I'm not sure how much help you're going to get, OP.
