I disagree. While there is a LOT of adult-oriented content it is also long hair. If you are seeking a non-adult long hair forum I would suggest yahoo groups where you can join floorlengthhair2 or any of the dozens of forums where they share long hair only.

Here, however, they have a broader definition of sources. And many of them are adult in nature. Offended by porn, you should not participate, but if you want the widest possible range of long hair sources...then welcome aboard!
