That would have a better way to say it, and I'll do that in the future instead of giving up.
I think Junko is so bad that they are a liability to both mafia and town, so I can't say that they are working for anyone but themselves. I'd think its possible they are a third party role, but I don't think those types of roles were included in the setup. They have jumped around too much and appear to have no particular goals in mind.
I believe you had a responsibility to smack them whether they spoke to you or not, so I'm wondering why you didn't smack them when you read the thread yourself. I know you read the thread multiple times and had actual incentive to watch your mentee's posts more than others. I don't buy that you had to look that up, and given that you looked at ISOs, I know you know you are correct.
Why are you posturing?
