Does this vulnerability affect people who added a phone number but then removed them? Last time I tried, this method was effective for getting around the "suspicious activity" lock.
Even if you disconnect the number, they still keep it on file.
I have a small network of legitimate accounts that they've suspended a few times. In this last round of suspensions, I can't reset any of them with my phone numbers any more.
No, it wouldn't work. It only works if people can discover you with the "find people you know from your address book" feature. A deleted number won't match. Or you can just turn it off in your discoverability settings.
