You first order some private proxies,
You then need sim cards for the accounts.
You then create a gmail account with 1 proxie then enter the mobile sim card number.
Remeber keep info on file 1 proxie and 1 sms for each account.
You can download a proxie selector for firefox this allows you ,to select the privete proxie using at the time of creating the account.
Every time you create a account ,please run tge free app ccleaner to clean all browser info.
A lot ppl just buy there accounts ,as it easer and in some cases a lot less money ,but if you got lots of social accounts ,creating accounts from the same proxie is fine ,creating other email provider accounts is fine ,so in that instance good value and right to do it your self.....
Good luck redarrow.
