Facebook's "Like" buttons track you across the internet, even if you don't have an account. There's no way to opt-out of that, and there's no way to download or see that tracking data. If you don't have an account, other people can still tag you in photos and you can't opt-out (opting out requires having an account). The profile dump also doesn't tell you which "deleted" messages FB still has on the server because the other person hasn't deleted them. That dump is not even close to complete.
