I'm pretty sure rate-limiting or blocking something using IP is not robust at all (except you wanna protect from teenagers?)

IP proxies are sold for cheap en masse, datacenter, residential, regional, whatever filter you like.

Have you even attempted to scrape Instagram? You're just throwing hypotheticals at me, but the reality is different if you even attempted to do it.

I'm pretty sure because I scraped a lot of stuff, maybe not Instagram but I don't see how it's any different. Reality of protocols is quite stable, and as long as you can send HTTP requests to Instagram servers and get documents back, you can find a way to scale it.

Again, do it first, then talk. Everything you're saying is pure theory, which holds no substance here. Do it, then talk.
