Guy was in a time walking dungeon and decided to manually kick me from the party, due to not wanting to skip a boss so we could get the xp for completing objectives. Toxic players like this are what’s wrong with our community in general. Think twice with grouping with this player. Reported. If he does it to you do the same.
Naming people in the forums in callouts is actionable from what I’ve seen others say, so is trying to drum up support for mass reports, even if the person is doing something wrong. Careful. Really there’s not much that can be done about this. Ignore and move on is your best bet.
