I think now she's going to find out about all the hair cutting and pixie cut fetishists.

I do agree with admonishing people to use some common sense and good manners when communicating with anybody about anything. However, I also think it would be very limiting to try to have a rule here not to put readers on to places to view nice hair unless they are explicitly sexual. That would eliminate a lot of material. It would also be impossible to enforce, since people's idea of what is or isn't sexual can vary quite a bit.

For any who don't already know, if somebody posts obnoxious comments or messages to your YouTube vid, you can block the user, and/or make the video private. A blocked user can still view your videos, but they can't subscribe to your channel, post comments to videos on that channel, or message you.
