Yes, it's just the word "troll" mentioned by the poster on the meta board. I'm not looking for troll users, but fewer mentions of the word "troll" could mean the impact of their reduced activity on the forum especially in the meta board.
That's not a good metric though. Besides we'ave all got a tough-skin after years of seeing trolls on bitcointalk. I myself either ignore them or usually report their topics/comments and move on, trying not to waste my precious time feeding them.
If you really want to see the "troll army" wait for a price dip and pay a visit to speculation board specially during long periods when price doesn't go up...
