Except that holydarkness kinda "know-how", as his statement came from communications with several casinos reps themselves? And his mind is wide open.

Betby has been found to stir so many problems these days, with their questionable rulings, where a player is limited or restricted or got their fund withheld in one casino due to "a violation", but their bets on the other casino with same provider didn't face any issue. Those cases though, are different than yours. Your case is actually a clear one where Betby quite likely played by the book. You're marked by several casinos, your record are there with betby, and follow you to betpanda.

I guess I can ask my new-found betpanda contact about yours, just to be sure and clear the matter, but... emm... mehh, why bother? I'm "unethical", after all.
