IS_EXPR is an imported function, and runs in its own namespace. It doesn't see
your globals.
Rather than use IS_EXPR, you'd be better off writing a custom validator. An
added benefit of doing it that way is that you can include the overhead of
BADWORDS in the validator's execution code (not its init), so it only gets
executed when the validator is actually used.
Validators are easy to write. Choose a simple one from gluon/validators.py to
use as a template. I suggest IS_EQUAL_TO.
