After all, the same kid annoyed with Uncle Frank might in the next moment give a knee-jerk "Like" to a fake quote from Rick Santorum or Sarah Palin. And Facebook remembers, so the next link to come along that's popular with your political faction will get promoted right to the top. Your life becomes an endless stream of links telling you that everything you already believe is right, and there is no reason to ever question it. Your computer might as well have a mechanical arm that comes out and continually pats you on the back for being so awesome.
But you can still comment on other people's links, right, and set them straight? Not so fast -- users have reported seeing this after trying to comment on a friend's status:
"I really don't see how my balls aren't relevant to this!"
The comment in question wasn't inviting anyone to an underground Nazi get-together. But it did set off a spam filter, apparently because it was long and included three links. In other words, if you find yourself in a Facebook debate, the one thing that can get you filtered as spam is daring to give too much explanation or sources to back up what you're saying. It's probably best to just call everyone Nazis/communists and go on about your day.
