You are good with all of your 25 accounts because none are from the same casino, thus not multi-acc, and most importantly, you're probably doesn't have a prior with the provider. The OP though, arbing at one point, and I am quite sure they have the record of it. Thus, you can't compare your situation with his. It's like going through the airport where your name is not on the watchlist, while he has an interpol-issued warrant.
I hope that helps you understand the difference and the situation here.
But he isn't multi accounting? There is no difference in this situation.
If I signed up to betpanda I would also get the same treatment as I already used a betby, and they are mis-interpretting betby's messages.
The only difference between me and OP is that he's used betpanda and got scammed, and that he is using new email, wallet on signup.
He is not. They are not accusing him of multi-accounting too, if you bother to read this thread carefully [I guess you just jumped from the opening post and to the last page].
The problem was that OP caught by the provider of arbing, and he admitted that. Due to this being on their record in the past, be it in five or six years or one month ago, the mark followed him everywhere, across platforms. That's why he need to take several counter-measure [and failed] to stall Betby [through the casino] to recognize his fingerprints.
The problem here is not a multi-acc, nor the creation of accounts with different email addresses and wallets. The problem is the reason
why OP need to create accounts with different email addresses.
