You say it as if there is one option - to hammer facebook every sec :)) I am logging to FB for the last couple of monthes. Yes they suspended some unverified accounts, but others are working just fine as well as 500 test users for app. What you don't need is to load test FB :) but if you want to login to FB (for whatever reason you need) use some reasonable ramp-up. in my case 500 works just fine. less than 500 will cause some users not to be processed. And if your scripts are correct and you send requests with reasonable tamp-up they do not show you captchas. you can even confirm/allow app via test scripts in jmeter.
