How can I combat this type of harassment?

[Bluevann]

I am grouped with a Paladin that is not responding to any communication --- period. He is standing in the middle of Castrum Meridianum and isn't doing anything. 3 people have vote kicked him, and he just REJOINS US IMMEDIATELY using the join in progress option.

While Castrum Meridium isnt THAT hard, he is abusing us/the game and we can do nothing about it. Why is this acceptable?

>_< Ugh, this happened to me with a WHM in Brayflox too. Kept kicking him and he'd just keep coming back with In Progress. Kicked people should get a penalty before they can use DF again, really.
