Flickr tried this a while back and there was enormous backlash. They tried limiting your contacts to 5,000. They later rescinded the limit and changed it to you could have no more than 5,000 *non-reciprocal* contacts. Since most people don’t add spammers back, this easily deals with the spammers while letting those with larger social networks still manage their larger pool of contacts. A smarter way to deal with the problem.
