Shame I didn't report them. This happened several months ago. So it's too late now, don't even remember their names.

Seeing GMs reply that they can't do anything because of a difference in playstyles and such sapped my motivation to report people as well.

It's fine though, I've learned my lesson

If I know there's a premade, start a kick on them ASAP if they're causing any problems. I'd recommend others do the same as well, because the vote kick feature has a Yes bias. If it's 2 vs 2 people, whoever starts the kick first wins.

The person being voted on does not get a vote but the person starting the vote gets an automatic Yes...so, yeah.
