The accounts in the original post have now been suspended after a play review.
Thank you for the report.
Wow, nice eye by @SickOldIMLOF aka the Scumbag Slayer to spot this.
Thank you for reviewing it, gave me some peace of mind indeed. I was getting worried that not only there will be no response at all, but that my horrible run on weekend was a punishment for reporting it.
On a more serious note, knowing that security team is there to check stuff like this restored a lot of my faith in fair play on tables. I will now definitely try 10€ SNGs again in the future.
