According to the official Discord, “ACX has made the decision to close Booklore and step away.” Some contributors are working together on an unnamed replacement project.
For those not in the loop, Booklore was an app that for selfhosting book libraries. It had a nice UI. It was able to store metadata separately from the download files, so you could have an organized library without duplication. In recent weeks, there have been conflict about AI code, licensing, and general Discord nastiness.

Maybe the comment wasn’t synchronized with your instance yet, and I’m not sure if the bot identified a link like this or a link like https://google.com/, where in the markdown description they added the HTTPS explicitly.
And I don’t know if the bot suffers from the Scunthorpe problem, i.e. dumb bot.
