Do Posts Expire?

Really old posts maybe, but it might help to see which posts you are trying to comment on

Oldest post for me is this one from 5 years ago: https://lemmy.ca/post/375988

I was able to comment on it just now

  Edit: link took me somewhere strange :/
  
  Just checked: That post says 5 years, and I can see Otter's comment
Ultra anecdotal, but I once had issues because I was setting the language of a comment. Didn't get an error, it just wouldn't post. Something to look out for.
