It's not that I'm feeding anybody but for everyone interested in keeping this thread signal/noise ratio as high as possible, I've taken the liberty to quote the excellent Peter R's categorization of a particular kind of user:
A Taxonomy of the Troll
Class C bitcoin troll (lat. trollus minimus):
-How to recognize: Simple-minded FUD spreading, and juvenile insults.
-Recommended response: ignore, their trolling is obvious to everyone and occasionally humorous.
-Examples: falllllling, Chuckee, fonzie (in the earlier part of his career)
Class B bitcoin troll (lat. trollus averagus)
-How to recognize: bait-and-switch thread titles and well-executed concern trolling; methods designed to fool the reader into thinking the troll is a non-troll.
-Recommended response: agree with everything they say in a satirical way. Their arguments are usually so flawed that simply rephrasing back what they said will reveal their lunacy. This technique is especially effective if the troll doesn't recognize this attack vector until he's already sunken his ship.
-Examples: Nagle, JorgeStolfi, Edward50
Class A bitcoin troll (lat. trollus maximus)
-How to recognize: usually hold an esteemed position or a PhD.
-Recommended response: Engage in logical and polite debate. These are the most difficult trolls to defeat, so you must be patient. The truth will prevail.
-Examples: Mark Williams, Paul Krugman, Richard Murphy
