The primary thing you need to know when selecting Instagram proxies is that the social network is very picky about tracking your IPs, so for running multiple accounts you will need Residential proxies that will not be easily detected.
If you use bots for this mission, most likely we support it. To make sure, mention it to your account manager to get just the right set of proxies.
Once you establish your accounts, follow the most acceptable user practices to stay below the radars: don’t do massive posting on the first days after registration, do not engage in mass following or mass liking before it is safe.
Let your newly established accounts mature before all these marketing activities can be started.
