User blog comment:ForestFairy/How to Take the Fun Out of Trolling/@comment-3219540-20150606022329/@comment-24756040-20150606235058

I feel that giving the troll an unwanted reaction, one that doesn't satisfy them, per se, will upset them as well. Trolls on articles are most easily dealt with per your last point, undoing/reverting said edit(s) to the article. Trolls in blogs are a bit different, as unless you have certain rights, you can't simply remove their commentary. In this case, depriving them of attention or giving them an unwanted reaction (in a troll's mind) will suffice as well.
