I’ve been using the ‘Top 6 hour’ sort, and it pretty much avoids most of those posts as they have no activity. Blocking the bot accounts that still show up is then pretty easy.

You really shouldn’t have something kike SSHD open to the world, that’s just an unnecessary atrack surface. Instead, run a VPN on the server (or even one for a network if you have several servers on one subnet), connect to that then ssh to your server. The advantage is that a well setup VPN simply won’t respond to an invalid connection, and to an attacker, looks just like the firewall dropping the packet. Wireguard is good for this, and easy to configure. OpenVPN is pretty solid too.

They may not have taken the lemmy.ml domain back yet, but because the different instances are federated, you’ll still be able to see contents from an instance that’s gone.
