Trying to hit 5k to tiktok shop affiliate

No luck with USA, but I'm sure India etc will love my animated content

How do I hit these countries and not hit USA anymore till I hit 5k followers

Some people have success with VPN but the best way is get a proxy or just find and interact with alot of accounts from the target country.
Or even better, get a sim from that country and create the account with that sim in the phone.
