facebook account checker

Hello, I'm new to the forum, I've been interested in software for a long time. I saw that the software category was very passive, to be honest, I was expecting it to be more active. I will try to share as much as I can here. I offer a software that I prepared for Facebook a long time ago, free...

Does anyone know of any software that would check facebook accounts in bulk, to see if they are still valid or have been banned or dead/not available etc? Mod's if it's a wrong section then please move the thread :) Thanks!
