How if you keep on winning and doubling your $80k profit? As you have said yourself that it is pure luck game, you cant prove that your account is flagged and adjusted to lose just because you lost what you have won before. Nothing you can do except accept the fact and blame yourself for not stopping after you made decent profit.
Do you know how to read? When you start winning they flag your account. This isn't a quick martingale on high bankroll. These are small batches of bankroll put in play over hundreds of thousands of rolls.
If you feel that your victory is marked, why do you continue playing it, even though you know that your victory is marked there, I think this is also difficult to explain the truth, you should also stop playing when you win at that time and leave it for some time then play again. I'm not defending anyone but I don't think it's worth complaining about our loss in this thread either.
