I am not quite sure if you are familiar with what "being limited" means in terms of sports betting.
A casino/sportsbook, can decide to limit your account to only be able to bet a specific amount on sports.
I know exactly what being limited means and that was my point this whole time. Your first account got limited to restrict you to bet no more than X on sports, so you created a second one to get greater limits and bet XXX. That is the reason for account closure. The first account wouldn't allow you to wager $10.000 because of the limits, and you wanted to do it through the second one. Whether or not you succeeded, I don't know. You say you didn't, but the intention was clearly there.
On a normal site that doesn't allow multi-accounting, I will accept this and leave their platform. On Rollbit tho, it was fine to replace an old account with a new one to get better limits. Which I have repeated like 25 times now.
I don't think it was fine to do it. It could surely be considered a nefarious use of their services.
