The solution? Make your own party or run the thing with your FC friends.

The PF, like the DF, is one of those places where you just roll the dice, especially if you are joining a party someone else put together. You don't get to join a party started by someone else and then lecture them on how to label their party. If you feel that strongly, then the answer is to make your own party and clearly label it so that you only play with other players that you deem acceptable.

Why does this conversation keep coming up when the solutions are so simple? You aren't going to effect change by complaining on the forums that a party you joined wasn't as good as you'd hoped.
