Apparently in Canada, people on self-exclusion lists used to be able to keep jackpot winnings. This has changed. Self-exclusion lists don't work, aren't supposed to work. I think casinos intimidate people by banning them nationwide from ever admitting a problem. It's usually the case the casino too close to home is the real problem but people can't just be barred from that one, usually have to leave the entire state.
Looks like sh!t just got imaginary!
