I told Facebook to delete my account as soon as they implemented this feature, years ago, and I found that (at least at the time) I could not block it on my Android phone. So, at least, I've not since then been party to giving Facebook information (they most likely have anyway) about other people, since the Facebook app is not installed on my phone.
