I have said it before and I'll say it again: if somebody wants to be rude in one of my runs, they need to prepare to be dumped out at the bottom of the queue because my life is too short to feed their sense of self-entitlement. Their entitlement ends where it interferes with any other person's ability to enjoy the game.
The ONLY people who are feeling "entitled" are the ones on either side of this who refuse to accept the other side.
Both spacebar spammers and the lonely who wanna watch the videos for the 100th time, are fully ENTITLED to play the way they like. The group is also ENTITLED to react how they want, including kicking either of these people.
It's an MMO. When you do things as a group, group majority rules.
