Criminal street gang members threatening and dissing each other doesn't qualify as trolling. If we're calling that trolling now then the term has lost all meaning. And that retiring US Attorney didn't cite any evidence of one social media system being worse than the others.

"Trolling: A person who posts inflammatory or otherwise unwanted material on an electronic forum, especially anonymously."

"Troll: One who posts a deliberately provocative message to a newsgroup or message board with the intention of causing maximum disruption and argument."

There's been an absolute epidemic within this thread of people attempting to redefine trolling in such a way as to minimise either the problem or the source article. It's beyond stupid, beyond credible, and beyond sustaining any credibility of those doing it.

For some reason, most of what I'd posted to the above comment (quotes from the letter) don't appear to have made it through. Sigh.
