Allow blacklist to hide spammers abusing Party Finder

[TaranTatsuuchi]

...
For those saying SE needs to do more, you need to look into studying some law. They aren't breaking any rules and thus banning them opens SE up to lawsuits stripping them of cash we need to improve/expand the game.

Actually, by requiring other players to contact them outside of game they are insinuating that they're doing something they don't want to show up on the game logs.
Such as, selling this content for real money, or participating in RMT to get the gil from the player on a different server due to them advertising across the entire datacenter.

And those would indeed be violations to SE's ToS.
