I was the guy yesterday who posted on the forum about the spoofing myth of Niantic. What I basically said is that Niantic can implement a machine learning solution to detect the majority of spoofers and the refusal to do so implies a monetary incentive to keep cheaters in play. For those who don't know, a machine learning algorithm is not explicitly programmed, but observes the human behavior and adapts/evolves accordingly to do a task (e.g recommend a movie, a youtube video or in Niantic's case catch a fraud).
However, I was vehemently attacked by some wiseguys that this is not possible and started throwing me a bunch of technical nonsense like IP addresses/VPNs etc which of course are ineffective and that's why I didn't propose that. Some other guys proposed that AI is not the holy grail and innocent players may be banned too. That true, and can be overcomed by using an expert in AI. But the all-loving Niantic didn't hesitate to ban all rooted phones (and I think we can all agree rooting is not cheating).
So I tried to do a bit of research about Niantic and see myself what's the technical orientation of the employees. The best source to do that is Linkedin. I searched the profiles of all 108 employees at Niantic to see their technical skills https://www.linkedin.com/search/results/people/?facetCurrentCompany=10149011 . My suspicions were true. I didn't find a single person with skills in machine learning/AI/data science. This does not prove anything....yet.
Niantic a few weeks ago posted 3 positions for highly qualified PHDs machine learning engineers https://www.nianticlabs.com/jobs/machine-learning-engineer/. I am sure that at least one of them will be used in the field of fraud detection.
So now it makes sense. Niantic probably so far has not used any AI expertise to their advantage, and all the spoofers so far are banned because of network analysis, which is partly effective. I hope that these new employed data scientists start firing up Hadoop and Spark clusters in order to eradicate all frauds who ruin our game.
