I was commenting on a question where a user had used some language that some people may find offensive when I realised I didn't know what Information Security's policy was on the use of swearing in answers. I have been unable to find anything to confirm or deny either way, so instead of assuming IS has the same policy as some of the other sites, I'm here to ask for a 'canonical' answer which future users can refer back to.
What is Information Security's policy regarding the use of swearing/expletives?
(In particular, is swearing for emphasis considered to be acceptable, a grey area or outlawed?)
(Also, I considered adding the answer-quality tag but was unsure if that would apply here.)
