There are literally millions of "trigger-pullers" out there on the net; hostile people who love nothing more than to get under your skin and mess you up as much as they can. Does anyone really not know this? If you don't know this, go read the comments sections of any less-than-reputable net publication or blog, of which there are an infinite number. Comments sections are the gladiator pits of modern times, and every participant is a gladiator. Except that nobody has any armor and most sensitive people stay away from such comment areas. You wouldn't know this from PC, which is a very protected place. Nor from places where comments are moderated. But other places can get very ugly indeed. Take care!
