One more reason I avoid sites like facebook and myspace. In the first place I would not like to be peppered with advertising at my "own" page. There's the lack of time issue. And then, there's the fact that your access can be revoked at any time, for unstated reasons. It's almost like they're the government, citing "security reasons," so that users have no idea why they are banned, and can never discover the reason.
