How can I combat this type of harassment?

Sounds like you are trying to harass a 1st-timer tank trying to watch cutscenes. They need to disable vote kick when people are watching cutscenes, just like you can't bring it during combat.

I'll be honest with you, in my experience i never came across a group that would kick someone just because they are watching cutscenes, most of the times they are just left behind or in some very rare cases they wait for them.

But if they aren't in a cutscene and are just afk far too long without warning the group then i would just start a vote kick, a quick "brb" doesn't take more than 2 seconds to type. There's a couple of people that tries to get a free myth ride in the main scenario roulette without doing literally nothing, some are even ninja and put /follow in the healer and only comes back in the last boss to exit the dungeon, yep i've seen that.
