EDIT: To be completely sure that you've PVA'ed your accounts the right way, you can check by going to http://developers.facebook.com and clicking on the "Register" button in the top right. After that, accept the terms and conditions of a Facebook developer account and go to the next screen. If Facebook asks you to verify your phone number, you did it wrong and Facebook does not see your account as a PVA account. If Facebook says you've registered successfully and you get to the "Add a New App" screen, then you've followed the guide correctly and your account is PVA'ed. To do a little bit of testing, I've been creating and buying non-PVA Facebook accounts and PVA'ing them myself. A couple days ago, I came across something that I think is really important. As a little bit of background, most people on BHW know how easy it can be to get throw-away numbers through things like app cloning, device spoofing, or proxies (depending on the app), and how hard or expensive it can be to get those same numbers phone numbers for extended periods of time. Many people run into a huge problem when they try verify Facebook accounts using throwaway numbers, because leaving a phone number on your account can lock the account if phone verification is needed and you no longer have access to that number. If somebody phone verifies 100 accounts with 100 different phone numbers and then loses access to all of the numbers, if Facebook ever gives any of the accounts phone verification they will be locked permanently. This is because when you have a PVA'ed Facebook account and your number is attached to your profile, this becomes the only method of identity verification that Facebook allows you to use. However, if you don't PVA your account then you can't do anything on Facebook without getting your account locked until you're asked for phone verification. The solution? When you PVA your Facebook accounts, remove the phone number afterward if you're not going to have access to it in the future. When you do this, Facebook won't force you to use the exact same number you PVA'ed with if asked for verification in the future, and it will also treat your account as if it has a phone number attached to it (no strict filters or phone verification prompts within 24 hours of doing anything significant). It's the best of both worlds, and you don't lose everything if you lose your numbers.
