I've been told by a GM that blacklisting someone prevents you from being matched with them in Duty Finder. I haven't ever been matched with someone on my blacklist before, so I can neither confirm nor deny the validity of that claim. GMs aren't infallible so some times they do give out the wrong information, but I'd be more inclined to lean toward the GM's answer on that matter. I haven't blacklisted many people, but I did have to blacklist a stalker, who still finds me through player search and goes EVERYWHERE I do (GM apparently still hasn't done anything after 3 sexual harassment reports, and same GM responded each time....), and have never been matched with him. Could be luck, could be blacklist. Who knows.
Either way, chances of running in to him through Duty Finder are still slim to none.
