A lot of things have reduced since the introduction of the merit system/over the past few years and it's quite interesting.
-snip-
Actually I don't think that the merit system has kept trolls away from the forum. The merit system has managed to keep spammers out of rankings, while their trolls don't care about rankings although this system can be blamed on their interpretation.
What 'troll words' were you looking for?
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.
While I do feel that trolling has decreased over the last couple of years it does not seem to me that it is as low as your numbers show.
That or I am just less tolerant to the edge cases where it might not be trolling, it just feels like it is.
I'm just looking for a specific mention of the word "troll" in the meta and not mentioning how many troll users are and their presence on the forum. As troll activity declines, I'm sure the mention of the word "troll" among posters will also decrease.
