Yeah, I think they employ a pretty sophisticated bot detection algorithm. I vaguely remember there being this 'make 5 friends' objective, or something along those lines, which I had no intention of fulfilling. If a new account, having triggered the manual reviewing process, doesn't adhere to common usage patterns, simply have them supply additional information. Any collateral damage simply means additional data, to be appended to Facebook's self-profiling platform... I mean, what else would one expect when Facebook's first outside investor was Palentir's Peter Thiel?
