Actually, it's not. You just put them on ignore and you don't even have to scroll past the drivel. The negative is you have to log in to have it work; if you just read, it's all there.
I don't like to put people on ignore, but I like even less having to scroll past a dozen or more posts of garbage to get to a post containing something worth discussing/reading, and then having to go through another 10 of garbage again. The ignores have earned their place on the list.
