No, my implementation (it’s still a WIP) doesn’t support sending “Update"s and “Delete"s yet. It’s one thing that bothers me about ActivityPub. Webmention is so much simpler in that regard. There also seems to be no way of forcing Mastodon to refetch an activity object other than sending an “Update” or “Delete” activity.

Just a small note: I deleted my Microblog.pub instance. I liked this piece of software and it’s a nice single-user alternative to Mastodon, but I don’t need a Fediverse instance anymore. My new fediverse strategy is to use my normal blog to post stuff (you can follow me via @en@jlelse.blog and @de@jlelse.blog) and Miniflux to follow people (Mastodon offers RSS user feeds).
If you reply to posts or mention my user handle in a public post on Mastodon, I will receive a notification and your reply will appear in the “Interaction” section under the post. If you interact with a post on your website and don’t automatically send Webmentions, you can also submit the URL in the form below each post.
By removing Microblog.pub from my server it also reduces the need for resources a lot. Python as well as MongoDB don’t seem to be that resource friendly. I currently use the cheapest VPS option from Hetzner and for the few remaining things hosted there (my website, my blog and some Go tools etc.), it’s more than enough.
