I don't know how you're set up, but when I did database backed web development back in 2001, actually deleting all of a user's information was non-trivial. It would either mess up the integrity of the database, causing unpredictable errors later, or would involve long, costly delete cascades. So when sites like Facebook just de-activate you, I just assume it's because it is a pain in the ass to actually do the delete, not that they really care that much about keeping your data around to give to the CIA later... So... I dunno, with your site, CAN you actually delete everything without it being a huge technical burden to do so?
