Specifically, https://superuser.com/questions/923377/cant-login-on-server-using-ssh-too-many-authentication-failures is a duplicate of https://serverfault.com/questions/580753/ssh-aborts-with-too-many-authentication-failures#580864.

I can't flag it as a duplicate, because the other question is on a separate site. Do I answer it? Do I direct to the other question in a comment? Do I try to attract a moderator's attention some way?
