This is just kid stuff, someone who's tired of making mommy cry because he's such a "good boy, really and he didn't mean it."
The other kids, while they CAN identify the troll, cannot yet resist the urge to feed it despite the fact that they themselves continue that which they claim to so dislike. In their misguided efforts to oust the unpleasant squatter they over-indulge in that newly found and oh-so-wonderful hormone testosterone. For many of the posters to which group those of whom you expressed displeasure belong, it is their first foray into the world with their newfound but misunderstood strength.
Some will catch on and stop feeding the little bugger. Others will think they can single handedly vanquish this loathsome foe, much to the dismay of those of us who witness these often trite, mundane forays into witty banter.
This type of thing is also a good indicator of the type of inner workings different people have.
Of course, interpreting those indicators, which can, and often do, appear different to each interpretor, can be tricksy. Very very tricksy.
