Sure, more analytics than just the one I provide here has to be included if we want to determine if the behaviour is human or not.
What I'm sceptical about in the example I provided here is the stamina to keep playing so many accounts so fast for a long time. The guy plays almost 12 hours in one go in the latest session (small break in the middle there), with 6 accounts at a time. But perhaps there are people who will do this.
That said, the purpose of this post was just to provide a tool to the community, not to pursue this player in particular :)
Now that's a different thing, and it sounds ropey. Do the accounts win a large percentage of the games?
Not really, the win rate on average for these accounts was just below 50% (47.3%), so that's not suspicious.
