Wow. You really have to stop drinking the Kool-Aid. This actually was the first thing they did, and very possibly the only thing they've done specific to Pokemon. Niantic uses the same techniques they used for Ingress to deal with GPS spoofers, and they're not that advanced. Play for an unrealistically long period of time without stopping and you might get a tempban and flagged for careful examination. Appear to travel at jet plane speeds by performing non-idempotent actions without stopping by an airport first, or doing this too many times in a short period, and you'll also get flagged for possible banning. Beyond that, they're really not doing much and it doesn't really qualify as "advanced localtion anomaly detection". You're giving Niantic far too much credit.
