Wow I actually never remember enabling this and don’t think I ever did either

very relieved to see I've never by mistake sent my adresbook to FB. However, that doesn't count out others who might did with my data in there. Probably not really GDPR-proof.

Same. Unfortunately my number is probably up there from someone else uploading it :/
