Are there scams that originate from Instagram?

This may be a dumb question, as scams are everywhere it seems, but if this is one, I’m not seeing the angle.

Okay, so I am selling off a bunch of stuff and one of the places I post these items is on Facebook Marketplace. I recognize the obvious scammers such as “Please text my father at ### as he is interested in this item”. But today I saw responses from a couple of people that apparently originated from Instagram. I started to respond to one, but a warning message popped up telling me that I was responding to an Insta account and that there might be consequences for doing that. So I stopped.

So what is the scam here, if any? Is this just another phishing scheme or something worse? Or is it harmless?

Nothing unique to instragram.

maybe the risk is higher because Meta (new facebook company name) is yet to do anti-spam anti-scam to on instagram to the same level as on Facebook

The scam I have seen on instagram is people posting comments saying "@thisaccount gave me excellent financial advice and access to investments. I made $2595trillion in a day ! " so as to bait for people who trust an instagram account with their money.
