User blog comment:Category5hurricane/AD Portection for trolls/@comment-26686429-20120914013815

The problem with this is that you're accusing every single editor that comes to your wiki of being a troll, which will annoy a vast number of those users.

Also, telling someone "don't do this" - when they had no intentions of doing it in the first place may get them to do it (if you're that concerned about it, it might be fun to see your reaction, says the now troll).

Have a look at WP:BEANS for a better description of that.
