As far as I am aware, there hasn't been any complaints like that, at least reported to us admins and I'm pretty much on the site all day so if there had been reports of not liking bad words then it wasn't reported through us. The only complaints we get are double posting or so and so is back and spamming his hate (you know the guy that keeps creating accounts).
The problem we are having with the filter now doesn't have anything to do with how the filter was set up in the past. It was something recently put in because we found a huge amount of spam on some item pages. Anyone who tried to view the items would cause the site to go unresponsive because the server was trying to process all of it. An engineer would have to log in and kill the process for that sql query as it would just stay in a loop.
