I don't know if the OP is a troll, nor do I care really, but the OP does raise a good point.

There are some people who wouldn't classify as positive or negative, the ones who enter a thread and say nothing but stuff like "who cares", "literally who?" or "is this a Titanmen thread?". Those people are indeed non-constructive and aren't contributing to a thread at all. In the same vein, there are also 2 other types of non-constructive people, the ones that go "this game sucks, shut up" to any positive thread and the ones that go "this game is great, shut up" to any negative thread. There's also the people who go into threads for the sole purpose of attacking OP or anyone else in the thread.

But it's definitely hard to get everyone to behave courteously on the internet, so perhaps it's better to just ignore people that you don't like.
