Facebook Platform Support Request

Name: Facebook
Homepage: https://www.facebook.com
Short description: Support Facebook profile verification using permanent post permalinks.
Optional API documentation URL: N/A (scraping recommended instead of API)

Explanation

Add support for verifying Facebook profiles in Keyoxide.
Facebook posts have two link formats:

Preferred permanent permalink:
https://www.facebook.com/USERNAME/posts/pfbidabcdefghijklmnopqrstuvwxyzABCDEFGHJIKLMNOPQRSTUVWXYZ
Includes USERNAME (user ID or vanity name)
Contains permanent pfbid... post ID
Stable and tied to the user’s profile
Less reliable share link:
https://www.facebook.com/share/p/12345abcdef/
No USERNAME
More prone to breaking

Verification should use the permalink format with USERNAME for reliability.

How to get the permanent link

Login Facebook through desktop browser (mobile version, and Android apk version is not advisable)
Go to the specific post on your profile.
Look at your profile name above the post.
Hover the mouse cursor over the date & time below your name.
Click the date & time.
The browser’s address bar will now show the permanent post URL:
https://www.facebook.com/USERNAME/posts/pfbid....

Technical recommendation

Scrape the proof text directly from the permalink post (avoid Facebook API).
Proof text should contain an hashed proof, same as Twitter support implementation.
This ensures decentralized, reliable verification without API dependency.
