Inactive instagram account questions

Hello I’m thinking about purchasing an inactive instagram account claim, but I have a couple of questions because I have no idea what type of service I need.

I was told I needed someone to do a request via media portal. What is that exactly and why would it be better to do a media portal request vs without? What other ways are there to claim it?

Let’s say the handle was something like dribbling, where they uploaded clips involving basketball dribbling drills. Inactive for 4 years, what service do I need?
