For what you wanna do, each account needs a unique IP address to mimic "real" users, and using an emulator alone won’t cut it, Instagram’s algo detects device fingerprints. Using tools like https://www.ldplayer.net/ or https://www.ldplayer.net/features/multi-instance.html let you create separate emulator instances, each tied to a unique proxy.
For proxies, avoid "Super Proxy" apps, they’re too basic. Instead, use dedicated mobile/residential proxies (I prefer https://oxylabs.io/ or https://smartproxy.com/) and assign one proxy per emulator instance. Configure proxies at the system level via Wi-Fi settings in Android’s emulator menu. This ensures Instagram sees each account as a distinct device + IP combo. Finally, start with 2-3 accounts, test for a week, then scale. Rotate proxies weekly and avoid public/free proxies, they’re flagged instantly.
Good luck,
