@doesnmppsflt@doesnm.p.psf.lt Not sure which bug you’re referring to. 🤔 (Did I forget?)
Those long IDs like (#113797927355322708) are simply part of that feed. Looks like the author just dumps ActivityPub IDs into twtxt. I think this used to work in the past, but the corresponding spec (https://twtxt.dev/exts/hash-tag.html) has been deprecated and jenny doesn’t support – actually, jenny never supported that.
jenny can only group threads by exactly one criterium (because it writes a Message-ID
into the mail file) and that’s the regular twt hash. So, anything else, like people doing “#CoolTopic”, isn’t possible.
