10-20x doing it on 1.01. If someone from rollbit see its as an abuse, then its an abuse. It probably depend on who is managing the casino. Lets just say its under new management and they noticed your account doing all these to rank up and get benefits.
I'm wondering how you relate this where the casino got your info from Stake. Did stake also locked your account and now its rollbit doing the same thing? IF this is the case then you really have done the same abuse.
I personally do not see it as abuse at all. If they do not want players placing those types of bets, then they shouldn't offer them. A person can just as easily lose that bet, so they can ask for a refund if it loses? Obviously a casino is not going to refund your bet if you lose, but saying a player is abusing them for betting x1.01 is kinda crazy IMO. They should either remove those bets or disallow them to count towards promotions. Solves the issue.
