Probably often enough to be used to it, although it's still bad design and needs to be fixed. (I'm not sure why a non-public-facing system needed a profanity filter in the first place.) https://en.wikipedia.org/wiki/Scunthorpe_problem

I find it interesting that this Twitter bot seems to have the same problem in reverse: it can't reliably filter out things that aren't offensive.

Edit: Thinking about it, it's really still the same problem, i.e. false positives when trying to automatically determine whether or not a given string contains swearwords.
