If you check in lemvotes you can see some activity from time to time, so I don't think they are dead. It could be a federation issue but they at least appear to have logged in and had some vote activities in December.

Regardless they did not have a healthy relationship with Lemmy. They were averaging something on the order of 15 comments, per hour, per day. That's a comment every 4 minutes, all day, every day, for years.

Idk. We should still probably build something to remember them by. Or to piss on, depending on how you viewed them. They were very political and were doing a lot of "pre blaming" for the, at the time, election which hadn't happened yet. I think it may have broken them.
