I'm not sure if they track it but I think it's ran by a 3rd party company or some shit.
I play it legitly on multiple accounts on my phone in my downtime and haven't had any problems of being frozen. In a day I play on 5 to 20 accounts depending on how much time I have. They are all junky basic shells I bought hella cheap so if they get frozen it's not a huge deal. I also play a modded version I found on here so I save a lot of time playing
I play it on my main as well but I use my tablet for that and my phone for the shells.
I'm not sure if they helps it you out of not but I sure hope it does
