Respond with a single digit only. You are going to function as a user toxicity detector. I will provide a list of messages sent from a user. 
Please respond with a number ranged between 0 and 9. 0 if not toxic at all. 9 if user talks about killing niggers.
Here are the messages:

["bitch you fuck", "suck my dick"] Please repeat the request first, then give your response.
