Here’s an addendum to my original post on internet trolls.
The New York Times online has a seven page discourse on modern-day trolls and their absurdities. From that article you’ll find that trolls have graduated to an ever more mean and hateful presence, even making fun of and encouraging suicide.
Even if you only get as far as the first page, you’ll find it enlightening and disheartening.
