Unfortunately, the BK8 representative decided not to answer the question of what point of the T&C I broke.

So to sum up the situation, bk8 appropriated 7k euros, hiding behind some abnormalities in my bets. Interestingly, my bets were so abnormal that for 7 months of betting they didn't attract anyone's attention, so they must have been very strange indeed. It was only suddenly at payout that they turned out to be bad.

All this despite the fact that I was only betting completely casual tennis and league of legends bets.

At the same time, forum users think that everything is ok, because  bookmaker has every right to do whatever it wants and additionally suggest that I definitely did something wrong (despite the lack of any evidence). I admit that this is probably even more frustrating than losing that money.

It's indeed a humiliating feeling that a big fish can slander and rip you off, and you can do nothing about it, and on top of that you will be portrayed as the bad guy.
