Yeah unfortunately that’s huge problem when creating accounts. I used to create accounts with Jarvee, add different proxy to each account before account got created. It worked for me.
Jarvee works like a charm as long as the proxies are good. But jarvee takes a longer time than creating one on phone. May be a couple of mins more for each account creation
but the creation is efficient with Jarvee even if it takes some time, as Jaha and Gtamaster said, use a mail service and different proxies to create the accounts
