I am a long time arbitrage/valuebettor. I open new accounts, because soon or later, they will limit the accounts.
About Betby clones, most of them pays well. I'm anyway withdrawing the money with not too much winnings, maybe 2-3k in each account. They are so so soft, this is the reason why i'm using them.
I don't think there is much of a case here, then. You're flagged by the provider because you're [as you admitted yourself above] a long time arb-er and/or value bettor. This strategy is very much well known to be prohibited, a thing that is shared by many casinos. This should be a known situation for you, given you're a long time value-bettor.
Can you please help us understand here how is this case still should be considered as an active case, while you admitted yourself that you do breached their ToS, and the very reason why the bookmakers flagged you as suspicious?
