I have been pondering this as well. The problem with this approach is mostly as I see it that we let a few bad apples ruin the fun. The internet is great exactly because we share. The problem was facebook insistency on 1) using real names and 2) on getting people to add facebook like to their pages to help them track. The last trick they took from Google (analytics). Its not like they are alone in this, the whole tracking on the web is a big mess.
