Max bet limitation is really applied by the odds provider, not by the bookie. However, the mentioned article doesn't contain this information. I suggested him to read the article so that he can learn why his max bet limit has been reduced. Casino treat their sponsored ambassadors especially. They also treat the high roller especially. The sports betting manager of a bookie (or admin) can increase the max bet limit for a user by communicating with the odds provider. Live support can't do anything there.
Providing the odds isn't the only responsibility of a betting odds provider. Your account will be limited by odds provider if you continuously place bets on low risk. Your account will be blocked by the sportsbook if you always place bets on fixed matches, the sportsbook gets the information about this from the odds provider. Read the replies of Stunna in
this thread to make it clear.
I think everyone already knows or guesses that odds providers are monitoring match fixing because it's their job to provide the more accurate and reliable odds they can, but I didn't see in your thread someone claiming they are chasing and restricting bet winners. Moreover I don't think anyone will be limited by an odds provider or a casino, for continuously placing bets on low odds, many people are doing that, but risking $100 for $1 of expected winnings, on something unsure is certainly more juicy for the house than the customer, in most cases IMO. In addition what people "Profiling and segmenting customers as part of ongoing risk management" are doing if they are not chasing and restricting/locking winners?
