Since a week ago yes definitely, since yesterday I am not certain. Here is one notification that seems to go nowhere: https://piefed.social/post/995600, where the notification, received yesterday, said "Jean-Luc Plushcard New Post in tenforward@lemmy.world", yet I see that post neither in the modlog for the community (https://lemmy.world/modlog/526169) nor in the list of actual posts in it, on the original server (https://lemmy.world/c/tenforward). Even if the post changed its title, then (1) it can't be in the modlog bc the last rejection there is 7 days ago iirc, and (2) that should not change the URL link to it if it wasn't rejected. Perhaps then it was removed by the original poster? Also PieFed had that Cloudflare issue, I think it was yesterday? But I don't know if that is related.

Do you think this situation is a good one to report on?
