To compare, I looked up the estimates[1][2] on Facebook and if we use 170 million out of 1.4 billion, that's ~11.7%. That is in the ballpark of Twitter's 15% (48m/319m).
I guess if you make a popular service that doesn't require a credit-card payment or phone SMS text as a test for human verification, you should expect >10% of fake accounts even with state-of-the-art heuristics detection.
