lemm.ee has shut down at 00:14 UTC.
unfortunately I realized too late that I have had hundreds of saved links to posts and comments from there, so I did not have enough time to save them, but anyways it is interesting that maybe a third of the post links I could try were dead. I think linkrot is happening much faster here than on reddit, even if just counting deleted posts.
It’s not all the lemm.ee posts, just a significant amount of them.
also in the meantime I realized my hundreds of lemm.ee links are not actually links to lemm.ee hosted posts, but just links to the lemm.ee view of them. I was just very often copying the wrong link that still worked, but wasn’t the definitive one
