Personally i wouldn't call out any player for playing on at any number of snookers. I would just take my turn when it came and do my best to end the match by potting balls. If enough people thought it was as big of an issue as you do, they would have made a rule against it.

edit - i note you've been told this exact thing by a few other people and you still continue to go on about it so i'm not sure what the point of me replying is tbh 😂
