The problem is not the PrimeDice, the problem is within you. If you really want to stop gambling you should help yourself not to play again or seek professional if you really can't control it and upon checking the PrimeDice policy about Self-exclusion here's what I found:
You should not attempt or proceed to open any new accounts during your self-exclusion period, or indefinitely if a permanent self-exclusion has been selected.
of course the problem is with me, that's why it's called a gambling problem, in any case, the idea is not to accuse anyone, but to see the possibility of improving the self-exclusion system
