Swearing in itself is not disallowed by the terms of use, but quite a few wikis (like this one) have policies that don't allow it. Very bad swear words, such as slurs, are not allowed by the terms of use, and you could report those users to staff using Special:Contact, especially if they're used against someone. Looking at that thread, you could try to report it, and there is a chance that staff will at least take some action, but there are no guarantees.
