the problem with "smacking the troll down" as it's being portrayed now is you have now opened up a mighty ol' can of beans for yourself.
Your "new" followers will now expect the witty riposte, the troll bashing etc....how long before you become (through no fault of your own) the very thing you hate?
Something I have noticed when posting or responding to posts, I tend to talk freely on them as if I know them and they know me and probably more important GET
me. This has got me into some stupid arguments online and it has to be said IRL. When I reread some of the things I have posted I cringe, simply because what was on my mind and what I had wanted to say was so far removed from what was actually written it would've needed a dna test to verify it actually came from me. You can edit, but that is frowned upon, you can update, but that too is frowned upon. It would appear that once it has been posted it is cast in stone in some peoples minds.
The downside of social networks and possibly the internet in general, is that it allows for snap judgements/decisions to be made and posted for the entire world to see. Everyone thinks and says knee jerk reactionary stuff, that they regret almost instantly, in the heat of the moment.
Online it can seemingly never be retracted, but it can be blown out of proportion, taken out of context and as you have discovered develop a basterdized new life in seconds.
Ah well, IF things get too hairy dude, I suppose you can always retreat to a remote castle and sit and count your 580 mil whilst calling out "Damn you internet trolls, damn you all to hellllllllllllllllll"
Oh and add a "Muhahahahahahah"
to the end, for effect ;)
