jaduncan[m] Bear: I would imagine that the defender would promptly filter on the webmention headers. It would however maybe be good to ratelimit webmentions on the plugins etc. If something that isn't on a whitelist is (or appears to be) sending 5 webmentions a second, it's probably good to cut that out on the respondent end. Maybe even to just require the user to authorise continued mention display.
