Is there a way to ask for what information Facebook has of a non-user (like myself), ask to have it deleted, and ask Facebook to not collect information about me since I am not a user?
Now that everyone has a cell phone and keeps the same number forever, your phone number is the new social security number. Think of all the places social security numbers were used because they were a fixed identifier and how we now think that that was a bad idea. Laws were passed against companies using them. Giving out your phone number is the same problem except many companies have some legitimate reason to collect it (see the article) and then what do you do?
Something that I haven't seen mentioned before, though I've seen on my account. There's a time when I noticed that Facebook still had my number, so I removed it. When I removed it, FB replaced my number with a random number (which looked like a number of someone else in my country). Might have been a bug at the time, as that's not the case now.<p>That event when I knew that I had removed my number, but still found it active; made me not trust Facebook.
