Taxonomy Access Control module - don't display term instead of disabling it
There is an issue in the issue queue regarding (https://drupal.org/node/1209154) this where the maintainer has given some options for a potential fix and has tried a few options out, however there is still no proper fix for the problem.

The module already handles the back end and not allowing users to submit those values, the disabling is really only for visual reasons, so removing via js is a viable solution in this case.
