I am no facebook booster (I think it sucks), but you can always make a phony profile that doesn't actually contain any real user data for them to sell. This may in fact be a violation of the site's terms of use, but maybe that's a good thing.
You would be following a rich tradition of renegades who misused products that were socially harmful as a form of protest against those products. I can't think of any examples of such renegades off hand, but I'm sure they probably exist.
