I guess the decoder is more than the 208 bytes that this page uses..

But maybe you can misuse this and store a session ID / cookie in a favicon (give everyone a unique one) and survive some cookie cleanup and evade privacy restrictions?

Maybe you can still make it that the favicon looks like an image a little to not raise suspicion?

Favicons seem to be cached across private browsing sessions. Oh no

I'm tempted to think that only someone working for a company in the advertising industry could come up with that.

Must EVERYTHING be polluted by ad tech & privacy intrusions?
