I bought a proxy, cleared everything on my computer, and only used that proxy for one Facebook account. I was extremely careful with it but I logged in yesterday and I got hit with the required phone verification. I did my best to make the profile appear legit and there was no nudity. Uploaded a few photos. Joined some groups, exc. I wasn't spamming or even doing anything like that. The only thing I can think of is that I was getting 50-75 friend requests per day. Will accepting a large number of friend requests each day trigger the phone verification from Facebook?
