Actually, the '(Deleted)' name in the Blacklist does not occur if the character has been banned by SE - the banned character name will still be listed as normal. '(Deleted)' only shows up if the character has been actually completely deleted by the owner or if they move servers. So if your blacklist is full of RMT from ages ago, you could probably safely remove the oldest of the bunch, as they've probably long since been banned by SE. Occassionally I get a RMT tell on Balmung, but I guess because of Balmung's congestion RMT ironically find it hard to recreate new characters there.

Also DarkRain, you should remove those screenshots as SE does not condone 'public shaming' on this forum - it's classed as a ToS violation and could result in you being actually banned instead.
