Additionly SE should be able to implement a bad word filter wich applies only to the chars names so that al combination with pvp and bank
will be prohibited from the beginning and if they then trying to invite you randomly they should be reportable as "Random Bot Group Invtie".

Will be a second point in the list but should be a separate one since they are not the normal RMT bots which are spaming at the market places
there websites in the chat (which is still better as getting stupied invites but also not allowed).

I hope SE will implement a new solution as soon as possible.
