Interestingly these "loves" (and I suspect other reactions) from Facebook aren't parsed as webmentions (I'm guessing by semantic linkbacks plugin) as the comment_type in wp_comments is empty rather than "webmention", but they are assigned a semantic_linkbacks_type of "reply". I suspect that this is why they're not categorized in the webmention section. I'm not sure what the bug is for giving all the names the same URL....
