oh I think I see a potential issue here:

I used to use WriteFreely on that ActivityPub domains before but now it's on Madblog, of course with a different signing key.
I see that your instance still cached some old posts of mine from the time the blog was on WriteFreely, but I can't search for new URLs.
I think that something off is happening on your instance because I can see that the cached version of my blog profile has now the updated profile fields (so it accepted the updates from my blog), but the latest cached post is from 2024 (and I've written more since then, both on WriteFreely and Madblog) and it can't find new ones.
