Clan propaganda in open invites

There are 3 open invites at the moment with a message like "our clan is recruiting", or "join this clan" etc.
All fine with me, BUT 2 of these open invites are for 2500+ players, and there are none of those yet, and the other is 2400-2500 with 1 day time-out; none of the top players will ever pick it.
This leads me to the conclusion that the open invite system is beeing abused.

I'd either have them removed, which probably won't solve anything because they'll just create new, or remove the option to put a msg with it completely, but that will only cause more complaints. Any suggestions?

I don't know what to do, either, but I agree, it's really annoying. I don't see how removing the option to "title" the game would hurt...

Impossible or almost impossible invites like that are removed periodically.
