Within the game logs, each account holds distance traveled and where a dinosaur was engaged. So for example you’re in Paris and you encounter a T-Rex and you visit a website to find the location as to where another T-Rex is located and you see it’s in London, you then jump from Paris to London within a few seconds.
This data is recorded and then Ludia just run scripts within the database to detect those players who are jumping hundreds to thousands of miles within inhumanly speed. Most cases they will not just ban 1 person at a time, but it will result in them gathering data for hundreds of thousands of players and then just ban them all at once.
It’s easier for them, but of course more frustrating for the average user as they think that nothing is being done, but they’re working on daily basis to try and combat people cheating.
