After about a year of saying that I would, I finally went and removed the bad words filter. That means that it is now possible to curse (and say things like ihatejulia, which for some reason was on there).
That does not mean that you should curse, however. Profanity-laced posts will still be removed and infracted, depending on the tone. In most cases, you should censor yourself or use other words. While the limited use of swear words will skate by, we'll be judging based on what we feel is acceptable. By cursing, you'll be taking on the risk.
