After reading over a few things, it does seem unfair to punish a whole party simply because one person is hitting withdraw. I think they need to implement it where the person hitting withdraw is being punished, not the whole party. Who know's when it will be fixed though.

Still at the same time, this is SE's first way of combating trolls. It's not perfect, but it gets the point across. Unfortunately (well fortunate too), you can learn who the trolls on your servers are if you are using PF to set up groups for DF.
