Yeah, it could definitely be used badly and there is a thin line between account management and growth-bot spam.

But that is part of what makes it interesting to me. Instagram has real anti-abuse systems, rate limits, weird UI states, etc. It's just a good place to experiment, everyone knows about it and it's something I was interested in.

I was totally expecting to get the account banned quickly.

Although I just added a disclaimer to make it clear.
