I would probably make a separate email and free to play account- that way if you get banned you’ll have your original account safe and secure. I also think you should play in two separate devices, iPad and iPhone, or Samsung tablet and Samsung.
Whenever you’re playing too, you should turn off location services, turn off updates for apps and turn on a VPN for privacy
I just got banned for 168 hours the other day day, I was so disappointed because my original account already had great champs, but I wasn’t able to complete acts 6, variants or UC events because their PI was too low. another judgement call I made seeing that Marvel Contests is expensive and it’s nearly impossible to rank up champions
