User blog comment:ForestFairy/How to Take the Fun Out of Trolling/@comment-26394405-20150605120048

This doesn't really take into consideration two things.

1, persistency. It may take many weeks of ignoring for a troll to leave. Even then, it's almost giving him/her fuel, as they can use the abscence of evidence as evidence.

2, puppetry. I've known a few friends of mine to use puppets, occasionally on different computers, to troll various wikis. I'm not going to name names, but judging from their "results", I suppose one could say that clever puppeting is a nigh foolproof method.

Of course, this could all be complete and utter nonsense. She does not mention the "true" trolls, the kinds you find on (prepare yourselves) 4chan and Reddit.
