Yep, I done a recent boo boo and closed an an account under Everymatrix. I only excluded as I don't like leaving accounts open which have my banking details saved on them and every once in a while, I'll streamline which casino's I play with and perhaps 6 months down the line will have a shuffle round again and return.
Thrills and Superlenny are great sites and are pleasing to play there, but after trying Casino Cruise, depositing there and then being told my account is being closed as I had excluded on another Everymatrix site (not for gambling issues and was not told which site), it sort of forced me to exclude at Thrills and Superlenny to save any problems.
Yes, excluding does open a can of worms, even after the period has lapsed as I have unfortunately found out via Cassava sites. Likewise it is a pain closing your account as it stops (I presume) you from returning.
Personal choice for me as I am always worried about open casino accounts with my bank details on them and which I am not monitoring as I have decided to try somewhere else (more than likely just following certain games/preferences). It is a shame that excluding for 6 months is interpreted as 'you have a gambling problem' and restricts what you can do elsewhere.
