First, related to who make the “nasty” comments.

If the guys are swearing, using slang and so on, ban`em and that`s all. Pointing them with some edit – badge them as whatever it wont stop them until baned. Yet, those are not flamers, are “flamers wanna be”, as known as “trolls”. They are a shame for flamers community (yet some flamers use`em to stir things ).
If guys disagree or are vehemently against one`s opinion yet within the normal language limits, eventually ironical, will be wise to treat them with same “currency” and not edit them replys.
From this point of view, that plugin is on the edge – quite a bit not usefull.

sidenote – is often used inside flamers communities to make some “changes” to opponent`s outcome, so to make things boil faster. But as a quote, not editing; editing means war and trolls often not “work” alone ..

Second, from the point of view of both blogger and his main supporters (readers who are friends and ready to “step in” to defend blogger points of view), is far more advantages to fight back, if / as long as blogger have solid background to support his points. Often a such “exchange” is in favour of more traffic and sometime can pull out good ideas for a new post for future days.
Yet, only until discussions are in the limits of normal language.

Stand up, compete !
Language not fit ?
Ban and delete,
But don`t edit.

ps: thanks for the visit
