As it stands, trying to access `http://byond.com/members/{mem_name}` with either an invalid or inactive account name will just show the forums with an error nested in the page. https://i.imgur.com/CY0hUJ2.png

I would like to suggest that instead of randomly redirecting to the forums, it produces a 404 or other HTTP error, and provides a proper error page.

This would be beneficial to scripts that use ?format=text (for that matter, if it's easier/better to only change the behavior of errors when that is present, that would be great), as it would allow proper error reporting without having to use an HTML parser.
