Don't worry, I handed out my Instagram to some people who requested it and those connections fizzled out just as easily.
Could be down to me only ever checking it on a designated laptop once a week, but in my opinion, if it comes down to an Instagram account and regular app access, can't even exchange SMS numbers to text, then it's already a tenuous connection.
Funny enough, I didn't even make my own Instagram account. My friend really wanted me to be on Instagram so he went ahead, made it under my name, and handed me the keys. You probably can't do this nowadays due to security checks, unless you're Meta making a shadow profile kinda like my friend did for me. I'm just sitting on the shadow profile that would exist anyway, trying to contribute as little as possible.
