If our standard troll response was “Well, Bless Your Heart”, troll presence would be significantly reduced.
JMHO the practice of posting to/at trolls (whose only purpose is to waste time and disrupt) only compounds their effect.
I just scroll past 'em....until they become a nuisance.
Then I can call ABUSE on 'em with the added justification of a lack of engagement. (Mods seem to react more readily to those conditions.)
Then I can just sit and watch....and maybe even call MAGNUM on the deal.
Mean ol' bum, ain't I?
No,p the proper troll response is to ignore them.
