Anyone who posts that message gets an automatic unfollow from me. If some one follows me and they have that message on the first page of their tweets, I generally label them spammers and don't return the followers.

I can handle about 350 followers. I can't really follow any more than that and keep up with them. Twitter for me is generally about creating and maintaining relationships. I can't do that if I can't read the tweets of the people I want to create and maintaining them. I generally don't follow anyone with more than 1000 followers who follows me first. I generally label them as spammers and move on. (I've had to turn off notifications because I was getting too many of those notifications. They never reply to me. They don't appear to click through on links I post. They unfollow me if I don't return the follow. That's a spam follower. Twitter needs to punish those with 1,500+ followers who continue to follow when not followed first. Force them to put people on lists instead.)
