The internet will always be full of creepy perverts that take full advantage of their anonymity to send undesirable messages to these girls. I hate this fact and I hate that it puts the respectful part of the community in a negative light, tarring us all with the same brush.
That being said, we can't police strangers on the internet, they will do as they please whether we like it or not.
As for gathering legit people together in a community who love hair, we're already here.
