Slash communities not showing up in Interest searches?

According to a couple of people on my Friends list (who shall be nameless unless they choose to name themselves), Interest searches aren't turning up well-known slash communities, or individual journals that have this listed as an interest.

Is LJ up to its old tricks again?

You can weigh in here if you like.

(I have to wonder if LJ thinks its users are really THAT oblivious.)
