Well done joerj.
This is a trap that perpetuates the cycle of gambling. When you can say no, don’t want to know, that is progress. And as you so rightly say, we all have kept that backdoor open. When you can tick the five year exclusion or however long their maximum is, that will shut the door. Better still to back it up with an email to support to say u have a gambling problem. Most will shut the door on you quickly although some unscrupulous sites won’t.
Well done for not falling into the bonus money trap.
