This is perfect for trolling, especially those who do not need to be consistent themselves, as they are pseudonymous and faceless, meaning they are able to go from topic to topic, cherry-picking what they comment on and the views they take, even if they are in direct conflict with what they have said earlier. Because they aren't building a consistent persona, they don't need worry about all of their inconsistencies - as there is no accountability.
Couldn't agree more. I have facebook friends who will pick at my positions without ever establishing their own.
It seems 'Matt is wrong' is their only real position.
Looks like winning, but it's just sniping from the shadows.
For no reward except the boost to their misguided ego.
