In my opinion:
Thumbs Down & 2* overall rating
2* for communication (your note should have received a response, apology & changed behavior)
2* for House Rules (anything illegal is breaking a rule in my book, your rules may need some more meat for the future & you may should look into internet security before you get banned or fined by your provider)
2* for Cleanliness (bc rearranging your house and not putting it back is a housekeeping issue)
Some hosts would call out the specifics of the guest behavior that is cause for the bad reveiw "These guests were xxxxx (whatever nice thing you can manage to say about them here), but our internet service provider notified us that several illegal downloads happened during their stay and they rearranged quite a bit of our furniture and did not return items to their original locations."
Other hosts would keep it more simple "we would not welcome these guests to return"
