Webmention is a
W3C recommendation that describes a simple protocol to notify any URL when a website
links to it, and for web pages to request notifications when somebody links to them. Webmention was originally developed in the
IndieWebCamp community
and published as a
W3C working draft on January 12, 2016. As of January 12, 2017 it is a W3C recommendation.
Webmention enables authors to keep track of who is linking to, referring to, or commenting on their articles. By incorporating such comments from other sites, sites themselves provide
federated commenting functionality.

Sping (Trackback spam) since there is no authentication or verification possible with Trackbacks.
