Why is Unlicense not accepted?

[agj]

Hello! I tried adding my userscripts in my Github repo. Their metadata is @license Unlicense. This is one, for instance.

However, I get a 400 error with the message:

`@license` is not OSI primary and compatible in the metadata block(s).

After doing some digging in your codebase, I figured out it's a blacklisted license. Why is that? Also if the error message was more informative it'd be a big help figuring out the problem…

See https://opensource.org/faq#public-domain which is what Unlicense falls under.
