Honestly, this isn't even really a fix. Since it appears they're doing this at the same time every day once a day, all the AFK'ers need to do is remote connect to their PC, re-login and go AFK again. They will proceed to clog up the system until the following day when they repeat the process.

If SE really wants to "Fix" the issue they need to restructure their AFK timer.

It's also pretty garbage that it's being implemented on servers that don't need it. Even Gilgamesh really isn't that bad anymore. Max I've seen is a few hundred at peak times since early access ended.
