Will there even be a cross server black-list of sorts for duty finder?

We know the GM's can't take care of every little complaint we have as players. If SE implemented a black list for Duty finder for each data server, people could choose to black-list players who have been rude/harassing if they feel it's worth it.

When queue'ing up for duty finder it won't match players with those on their black list, and if players are consistently rude to other players they will find themselves having longer queue times and can only blame themselves for it. It might force players to think about their actions and remarks.
