my method is fresh accounts every day and using them in that same day , so you can so they are only usable for only 1 dayThese are IPs that real ISPs provide to home owners. They are pretty expensive but work well with Instagram, for account creation and running them.
Residential proxies have been IP addresses by a normal Internet Service Provider usually DSL and which are wired into your house.
They're good for any social media automation really.. depending on what BH activity, you could possibly get the ip blacklisted.. but if you have a good source for them, you can always replace them.Are they ok to use it with blackhat methods ?
