Quick summary

I created a post (https://epiph.yt/en/blog/2025/optimize-surge-configuration-for-activitypub/) where @obenland mentioned me afterwards. I answered via my blog. Another user answered the post of @obenland, too, and @obenland answered again – both answers were also published on my blog.

When @pfefferle answered on my first answer (https://mastodon.social/@pfefferle/114474115709842979?kjy=spring), my blog got no notification (this is also true for the next answer after that).

While I can see a POST request to my inbox 2 seconds later, I unfortunately cannot be sure that it’s really the data that should be responsible for creating a new comment afterwards:

[08/May/2025:20:33:06 +0000] "POST /en/wp-json/activitypub/1.0/actors/0/inbox HTTP/1.1" 202 12 "-" "Mastodon/4.4.0-nightly.2025-05-07-security (http.rb/5.2.0; +https://mastodon.social/)"
