I have seen some really funny ones, usually ironically to a post raising the point you just have, you will get a bunch of follow4follow replies.
I was trying to tell someone new the other week that number of followers isnt relevant, just write good posts and you will get people who are interested in your content, he agreed with me then asked for follow and upvotes; it was like talking to a wall.
Follow me and I follow you back. ha ha ;)
