They shouldn't have harassed you, I don't understand the need people have to point out and make snarky comments about a complete stranger for no reason. If the language gets bad just report, right click their name and ignore. At least you know you won't have to run into them again.
I ran it last night for the pet and ended up with a tank that just stood there the entire time, did nothing. No one said anything, we just kicked him. Got a new tank, moved on. Simple as that. No need to harass anyone.
