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.
That event when I knew that I had removed my number, but still found it active; made me not trust Facebook.
