From the start, no it didn't happen to me

, that's not why I am asking.
So, have you ever found yourself in a situation where, after getting profits month after month on a specific sport the bookie decided to limit you to something like $10 or $5 per bet while still allowing you to bet and deposit/withdraw? This does not take into consideration limits applied right after a deposit or after receiving bonuses, like most of the scandals in the reputation board, leave those out of this topic.
This is only addressed to people who have constantly won over long periods of time, that are in net profits, and have been slapped with a limit.
And full disclosure, I'm on a 4-figure profit over quite a few years with one of my horse racing bookie, I was just wondering if I finally cross the 5 digits mark, would they start looking over?

First, let’s be clear that bookmakers are businesses whose main goal is to make a profit, and when someone starts winning consistently, especially over a period of months or a year, it’s no surprise that they take steps to protect their own interests, such as limiting the maximum amount you can bet. After all, if you’re consistently in profit, you’re probably “breaking their business model.”
On the other hand, from an ethical point of view, this practice is quite “questionable” because when you create an account with a bookmaker, it’s expected that there will be a relationship of mutual trust: you bet within the rules, and they pay out your winnings. Limiting your bets just because you’re being successful may seem unfair, especially if you’re not using fraudulent methods or exploiting flaws in the system.
Now, back to your specific case: if you've been making 4-figure profits for years and you start to think about what happens if you cross the 5-figure mark, it's reasonable to assume that this could draw the attention of the bookmaker and I'm surprised that they haven't banned you completely yet

One thing I recommend in these cases is to diversify... if you already have a good track record with a bookmaker, it might be a good idea to spread your bets across different platforms to avoid a single bookmaker limiting your activities. Always keep a "low profile", avoiding sudden big movements so as not to attract too much attention.
But the question still remains... to what extent do bookmakers have the right to limit players who are making a profit? On the one hand, they are protecting their own interests; on the other, this could discourage loyal and experienced bettors. What do you think? Is there a middle ground that is fairer for both parties?
