The troll phenomenon is an intriguing (tho not fascinating) one. Is it not?
They post things that not even the most gullible person would buy into
(ala Trump) and delude themselves that they've achieved something
when in fact everybody other than a few other simpleton trolls, knows
there's absolutely no substance to their posts. And as you say, in the wake
of Pinky, Shinya, Talpa and a long line of troll clones, they're all chronically
ordinary, reading from the same standardized script. Ants from the same colony
as it were; yet another "Mouse that roared".
