Is there any country restriction on these account like I am from India, will it be a problem?
Why these accounts are shared, doesn't that increases the possibility of scam from your side? You can change the password anytime and go to another site to sell them again. You have to change this as you are selling them not renting them.
If your in india you will need a VPN, I am also outside the US and I use a VPN. I will also send you a link to get a free cracked VPN when you buy an account.
Shared accounts make it easier to afford the accounts, if the subscription is $15 and I sell each one for $5 the account subscription becomes free and I loose nothing and no reason for me to scam, I can sell each account up to 5 people to make some profit.
If your not happy with the method I use you can go and pay $15 every month for an account, this is for people who can't afford the full subscription fee.
