unfortunately for ignore to work, a united front is needed, that can be difficult to get. If you don't have everyone putting the troll, all that happens is that those that do have a hard time understand what is going on in conversations. I just think light moderation done by someone reasonable(not me), could solve some of these problems with trolls very quickly.

I'm not just saying pretend their posts don't exist. I mean actually use the ignore list function of this forum so that their posts are blocked for you.

Increasing the level of moderation for this sub-forum is like giving someone Oxycodone for a light headache.
