I've noticed that there are sites like Goonview that claim to let you access both public and private Instagram profiles without notifying the account owner or requiring you to follow them. I know that Instagram's official APIs require permission from the account owner to access their information. There used to be a way to view stories through a specific URL that returned JSON data, but it seems that endpoint is gone now. Initially, I thought these services might be using headless browsers like Puppeteer to log in, but when I checked my own account through Goonview, I didn't see any evidence of my profile being added to the story viewer list. So, how exactly do these services work?

Honestly, there's no legitimate way to view private profiles without their approval. If someone claims they can, it's likely a scam or they’re not being truthful.
From what I've gathered, Goonview is pretty sketchy. I actually came across some warnings that it's potentially a scam site, and users should exercise caution before trying it out.
I totally get your concern! I've seen claims like this before, but often it's just a gimmick or even malicious software. Be careful!

I tried it and it seemed okay, but I'd still be cautious about what info I share!
