I do wonder though, I myself registered at Rizk when I lived in my old apartment, but have now moved and have a new adress as well, so if they require documents from me does that mean they can deny me my winnings? Cus that makes zero sense if they could do so (I assume there must be something else to this story).
People do move now and then and never had any issues with my new adress on any casinos so far.
Hell, I accidently put in wrong year on my birthday at betsafe, i sent docs and they fixed it for me, no problems at all.
You maybe can edit your address yourself on the website, or just send an email and they change it for you. You should get it changed everywhere though. It's important.
This case is different and it sounds like he just choosed an address. We all have documents of some kind.
They can't rizk their license so whatever happens I hope people here have as much sence to realize it's definately not to try and steal but to follow regulations.
