Twitter Announces NFT Profile Pictures:

Twitter Blue:

You asked (a lot), so we made it. Now rolling out in Labs: NFT
Profile Pictures on iOS.

Such profile pictures will be identifiable by being hexagonal. (Android and web users are still locked out of Twitter Blue.)

Sam Biddle:

I predict a browser extension that auto-blocks people with
hexagonal avatars would become very popular very fast.

NFTBlocker:

This is a browser plugin that blocks people who use Twitter’s NFT
integration.
