If you’re banned, you automatically get logged out of the DevForum. Normally, when you log in, you should see a fail error message alongside the reason you were (temporarily) banned from the forum. This doesn’t happen, instead you get redirected to the login authorization page, stuck in an endless loop of redirects (that is, if you continue to try and log in).
I suppose it would be nice for a message to show up, as it did back in ~2021.
