Do they give limits really fast?
Yes. Comeon, Snabbare, same oddsprovider. Once you are limited on one you can ope account with clones but they will limit you fast.
How much is it possible make profit before ComeOn limits you? Approximately.
I was already limited at Snabbare so the limitation on ComeOn was faster. I actually lost about 100€ on them before I got limited. Think the account lasted less than 10 days. Only 150 bets.
