ok anyway i solved the problem: i changed from MEmu the imei and telephone number and after restart no more synchronization error.
But i think they do this until an human control will ban me.
That depend from your internet provider ...Do you have a static or dinamic ip? are you over NAT or do you have a pubblic ip?
I'm over NAT and probably is that the reason my another account dont be banned.
No resync errors?? Because in 1 day i had the lvl 10 castle but everytime i try to raid someone at the end of battle i got resync error and dont save the battle xp point.So i feel that soon i'll be banned. Anyway can't exp my titan with resync error.
Only one of my account was banned and i played over the same ip and i cheated in all my account. I think natural motion is not enought crazy to banned 50 players only because the ip.Probably there was an error.
