Postings, intentionally, NSFW images isn’t limited to gifs, or even images – one could make an ascii art image that is NSFW. I must still be missing something as I would assume that it should be super easy to have a talk with any employee who is doing anything NSFW at work/on work equipment and institute strict penalties if it is an ongoing issue. Removing everyone’s ability to leverage a (increasingly) common way to express intent/emotion/levity feels like the incorrect solution.
