Would being self excluded from poker stars effect PP
As I understand it, self-exclusion is done on a 'per licence' basis rather than the global group owner. It seems from looking at their site they don't share the same UK Licence.
Edited to add this, found on PaddyPower site:
Please note: Self-Exclusion does not cover Sky Betting & Gaming, PokerStars brands or Full Tilt Poker. You will need to self-exclude directly with the relevant brand in order to be excluded from your account with that brand.
Bet365 is still independent as far as I'm aware. PP and PS are part of Flutter.
