"running under screen" != "non-interactive".

No shit.  If you allow users to login at all, then (IMNSHO) removing
screen is insane.  That's not a solution to your problem, that's
creating a totally new problem and pretending it's a solution.

I essentially always use screen whenever I ssh to any Linux box for
any reason.  If my sysadmin arbitrarily disabled screen because some
other user was doing something dumb, I'd be pretty upset too.
(Annoyed enough to maybe just build screen myself on that box.)
