@julian wow, ok. That's really helpful - thanks!

@julian@activitypub.space Replying now because I only saw this thread today (h/t @reiver), but I don't think this is quite accurate as written regarding Mastodon.
AIUI, Mastodon decouples replying and notifying. If you reply to a post from a Mastodon server but do not tag the author of the parent post, they will be part of the ActivityPub recipient list (and their server will receive the reply), but if the parent poster is also on a Mastodon server, they will not receive a notification about the reply.

In other words, @paulgc, you should be seeing those Create activities if the reply comes from Mastodon. I think if you reply to a post on your server from https://activitypub.academy you can inspect the payload that gets sent.

@julian@fietkau.social @julian@activitypub.space @reiver Thanks - you're right, I am now seeing them. They turned up at the shared inbox, rather than the user's inbox, which is why I was missing them to start with. activitypub.academy looks useful!

@paulgc@mastodon.social yes, shared inbox is useful to reduce the number of requests sent.
NodeBB will always use a shared inbox if one can be found for the user.

@paulgc Glad it's working! Although now that I've tested it myself, I'm not quite as confident anymore. 🤔 A test reply I made at https://activitypub.academy/@begusla_laddaciul/115865414668779913 has the ActivityPub `to` set as the account's followers and `cc` to as.Public, but was sent to my server anyway. So I guess the behavior, at least on activitypub.academy, is to not individually address the parent poster, but send them a copy of the post anyway (presumably justified by W3C ActivityPub §7.1.3). Feels a bit funky.

@julian@fietkau.social @paulgc@mastodon.social mm, I don't suppose there's any reason addressees and delivery recipients need align.
You can't enforce it 😁
NodeBB does this too, where we'll send a copy of a reply to everybody in the immediate chain, even if they're not mentioned.

@julian@activitypub.space @paulgc I'm lucky none of my projects so far have needed to really deal with replies, so I haven't had to think about this. 😄
But it reminds me how I've been told that Misskey sends an account's likes to its followers in addition to the author of the liked post, which Mastodon does not. So on Misskey, if a post comes by your feed that someone you follow has previously liked, you see that information. That's cool in some ways and showcases implementation differences in activity delivery.

@julian@fietkau.social that's a great idea! I should adopt that, there's no downside.
-
@julian@activitypub.space @julian@fietkau.social well, in theory, you can have private likes and public likes. misskey and pleroma do public likes. mastodon does private likes, but then shows them publicly if anyone asks the origin site. because addressing is just a suggestion, apparently ;)

@julian perfect!
-
@js@podcastindex.social done and tested as working. Looking for the AP Accept headers now. Thanks for the suggestion :smile:
-
@evan @julian no it was just one that I found was allowed, after wasting too much time with trial and error
iirc they even had different rules for incoming from CF ips vs not, but it was a long time ago!

@js@podcastindex.social Although... now that you mention it, Anubis does have the ability to filter by header values, so I will update the bot policy file to allow the standard ActivityPub accept headers.

@js@podcastindex.social AI crawlers are hammering the site fairy regularly, and my options are to allocate additional resources or put something in front, otherwise my site is inaccessible for hours/days at a time.
Cool integrations are great until they hamper usability of the site 🫤 if the crawlers behaved a bit more like search engine crawlers I'd have no problem.
