Will I’m not sure if the rules have been updated but the original rules from the archives are here. I assume those are still applicable.
In terms of vulgarity, it depends on context (and often up to mod discretion when it gets into grey territory), but vulgarity leading to bullying will be dealt with seriously. For example, discussing swearing in the context of Eng Lang? That’s ok; kind of need to in that instance. Saying X user is a faggot? Not on, mate. There are a number of Years 7-9s (sometimes even younger than that!), who come to AN for advice too, so our audience isn’t always 16+, so please be mindful.
Oh, and 0.
