We could use a Preferred/Blocked player list for DF.

How often do you actually run into the same guys twice via DF??

The blacklisting part was only half of what I was suggesting.

I've run into a lot of nice players I would love to play with again but they're from other worlds.

I have met the same person in DF before though, I assume it's a bit more likely too if you're doing 8 member runs or CT.
