Seems like lately, the Zucc had made it extremely difficult and confusing to deactivate by obfuscating the links. Why is that? No one knows but it’s clear they want you to stay.
Quick access link to deactivation:
Facebook account: https://www.facebook.com/deactivate_delete_account
Also works for pages but you must be signed in to that page first!
WARNING: If you’re like me who reactivated an Instagram account to retrieve something then attempted to deactivate again, it will not work right away. It seems like Instagram has implemented a 7-day cooldown before you could deactivate again.
DISCLAIMER: These links may stop working soon.
