Here's what I do: I scroll past the posts that characterize someone new as "troll", that are just absurd, have no meaning or content, etc. There do seem to be a lot of folks lately that are pretty quick on the "troll" trigger, however. That being said, there have been quite a few trolls dropping by of late. Unless the posts are really obvious from a troll, I like to give the new poster the benefit of the doubt. After all, I was a newby once myself.
Roger that ~ me too!
