I actually mean it's probably the clients' fault for choosing the wrong relays. I haven't looked into it, but it could be that listr is sending your lists to non-outbox relays, which aren't checked — but are scraped and replicated. Lots of old band-aid solutions existed from before outbox gained adoption.

Ah! Ok. That makes sense. The most sticky & unstable of these lists do date back to when Listr had its last major makeover.
I'd back away from people lists, until last night. Coracle's controls for that are really nice. I'd completely missed it, in leui of playing other custom feeds. 😅
Yeah, I very much need to update feeds/lists. I do have something in the works
