@Edent I'm reading https://shkspr.mobi/blog/2022/12/the-ethics-of-syndicating-comments-using-webmentions/ and I haven't done anything to indicate I wouldn't be happy about web mentions, e.g. opted out of search engine indexing, so it seems ethical enough. I guess it also depends on who's doing the syndication- using oEmbed on a private blog might be over the top but it seems reasonable to expect commercial sites to have tighter controls.
