I missed that, last night.
For what it's worth, that word is supposed to be impossible here, as well. There's a short list of words (added by PC, for what it's worth - I quite deliberately passed on adding some other, borderline things) that are supposed to be automatically masked. At the moment (probably because of a bug in a version upgrade) that doesn't seem to be working.
More generally, Discourse encourages communities to self-regulate. There's a "flag" icon at the bottom of each post; if you find a post to be inappropriate or offensive, you can click the flag (any logged in user can do this) and the post will be brought to the attention of the moderators. If the moderators agree (we won't necessarily - individual users could flag a post for personal reasons, etc.), the software will record the incident against the offending user. If a user gets too many such "points" (which go away over time), the board will restrict that user's posting permissions... automatically.
So for the most part, managing offensive posting is - and should be - in the hands of the community, not a couple of "police" (moderators). Of course, this only works if the community understands this, and cares enough to use the available tools. If the community doesn't care...well, that's one of the things that defines what a community is, eh?
