Nope, nothing similar to these. I did not use any kind of strategies to gain advantage. Dont forget that the reason they dont pay me is because according to them they have indications for multiple accounts, nothing wrong with my bets etc.
A little fun fact ( I guess this might have been mentioned before in a different thread ), as long as you don't abuse any bonus or sports limit restrictions, it is allowed to have multiple accounts.

This rule isn't used frequently but should be for all casinos. Players may not even realize that they made multiple accounts. No harm, no foul.
