in order to protect problem gamblers from themselves, there is usually no reversal of self exclusion nor deletion. im sure degens throw all kinds of reasons at support for reinstatement, and letting them back would be dishonoring the players exclusion request. with that in mind, ive never heard of temporary exclusion. its a one way door.
black chip poker, true poker, and betonline(i believe, idk never played there) are all skins on the same Winning Poker Network. if you deleted through wpn support, youre probably screwed for those sites.
