I'll add onto Joe's response.
Just because you're okay with swears/nsfw content, does not mean everybody is. Sure...the majority of our members are laid back and don't think twice about swearing. However, you need to realize that this is a large community with all sorts of people in it.
We have parents with children, we have younger members, people who don't like swearing, women, men, cousins, uncles, pirates, spacemen, military, LGBTQ, priests, drunks, and everything in between. You need to be aware of the community as a whole.
Swearing is generally fine in chat...to an extent. We ask that you use your judgement and don't get out of line. Anything outside of "casual swearing", i.e. anything vulgar, offensive, or racist, is not tolerated at all.
It's more-so accepted in chat than in TeamSpeak. Mostly because a text-based chat is easier to keep down than audio. Not everybody uses headphones. It certainly wouldn't be good if you're dropping f-bombs all day when Montoya's kids walk by and hear you.
tl;dr:
-Okay: Casual swearing, to an extent.
-Not-Okay: Vulgar swears, racist/offensive comments. Porn. Getting out of hand on teamspeak.
-Don't piss off Pooh Bear.
