Buying aged facebook account for creating a developer account? - Personal account was flagged

Hi! So I bought an aged facebook account to try to create a developer account for a personal app. I did this after multiple attempts at creating a dev acc from my personal account (it got flagged cause it was like 2 months old, got the famous “logging in from a new device” bs… so i turned to this, unfortunately.

Anyway any advice to not get this one banned/flagged? I will wait to create the developer account (like 2 or 3 days maybe) and stuff but what else.

I know theres a risk cause the guy who sold it to me changed the name and stuff, also it has no friends so i added some ppl i know. But anything else I should do? Any warnings? I’ll be traveling soon so thats already like 2 IP address changes i guess (im not technical so correct me if im wrong)..

I’m not trying to scam anyone or commit fraud i just want an app that posts for me since I’m too busy to do it myself (dont wanna pay a sub to some app, this is why im creating my own)…

thanks
