If my memory serves me correctly, favicon used to automatically become the websites icon, no need to make a html link to it, it just automatically did it. Not anymore though, it might just be the way webservers handle it, or not. Either way, ulx forums does not have a favicon.
Actually...
I just tested with my little Raspberry Pi server---Chrome still actively seeks out
favicon.ico even when one isn't specified in the HTML.

<p>I exist solely to test if browsers automatically search for a favicon when loading a page.

But, yes.
forums.ulyssesmod.net does
not have a
favicon.ico at its root, nor does the HTML link to it.
ulyssesmod.net does, however. Yet, somehow, the majority of us still seem to have the favicon. I still have it after resetting my favicon cache, and browsing data.
