I don't see how it's offensive or vulgar. Remember, that feature exists to report things which are offensive or vulgar OOC. Insults delivered IC that are lacking in expletives, racist epithets, sexist languages, or other hate speech should probably not be reported.
I will be sending a message to Tom in just a moment because the needs to be cleared up. I am sure Anaris said or agreed to vulgarity being IC and its been talked about before so it needs clarification by Tom and IMO, an announcement made for it too.
