This can't be a serious post...
I suspect he is questioning your post because it has been said time and time again here in this section that a PVA account does not guarantee that you will never receive a captcha again. Over the course of your 2 months of friend adding, FB has obviously caught on and now they are requiring you to enter captcha, PVA account or not. This is not uncommon, and has been covered here time and time again. I'm sure it will also need to be covered a hundred more times before everyone understands.
