Please define "site", "site admin" and "to post
from a site" unambiguously, and please explain the

If the so-called "spam attack" doesn't carry a valid
signature, everyone can recognize that it didn't
come from "your site". Not a cancel issue.

The first three items you listed didn't provide

See above.
