It might take time for a sportsbook provider to realize that username "holy" on Rollbit is the same person as username "darkness" in, let's say, BetPanda, and UID 12345678 on BC. But eventually algorithm will caught them, and thus, even without offense on Shuffle or BC or BetCoin or DuckDice or other casino who share same provider, the "presumption" [or rather... judgment] will eventually fall to "darkness" and "UID 12345678" in form of either ban-hammer or being limited.
Makes sense, but they should make it clear to the gamblers in question instead of asking them to specify their other accounts. This is usually how
arbers get caught across sportsbooks with a common provider.
OK, THIS MAKES SENSE NOW!
I believe we have answered our own questions. Plus if the individual who is complaining is an actual ARBER who does it professionally and does it with a group of people to escape detection, THEN we definitely know that they're not mere plebs like us that have gotten their accounts locked. The provider is actually trying to stop toxicity that's exploiting their system.
