Can you even create fake Facebook accounts these days? I have a real one that I never verified years ago, and Facebook would always ask for verification, but allow the account to still be used. However, I tried to create a fake one, and within hours, Facebook locked the account, and claimed it needed to be verified with a phone number to continue. I tried it a few times, from different IPs, and they required a phone number within a day for each account.

You could buy a throw away cell phone for verification, which is what some people do after I did a little research, but it's more effort than I'm willing to spend.

These were not obvious fake accounts, I create a realistic fake name, location, and a couple of interests. At the time, it seemed all new accounts would require a phone number shortly after registration. I imagine it's still the same.

In conclusion, I just don't use Facebook. If I'm not willing to bend over and give up my privacy, they don't want my business. So, I don't use them, and don't implement anything Facebook related across my sites.
