I'll applaud but note that the Report Abuse button: a) Has been there for a very long time and b) Has been (at least for me) remarkably swift and effective.
YMMV of course since I habitually lurk far more than post, NEVER EVER EVER engage a troll and only RA 'em after checking their posting history plus allowing at least three substantive violations (cursing, flaming, distractions, etc) of "civil" posting protocols.
JMHO the number of regulars who Feed the Troll (except for JediMaster Bagster) sometimes disrupt the thread more than the troll....
