Problem one: If it is illegal where this site is hosted I have no way of knowing that. That's up to the site administration to handle in that case.
Problem two: This is already a website for the purpose of exploring a variety of obscure fetishes. Yeah, we may feel we're better than this guy...but I assure you, to an outsider, we all look about equally fucked up.
Problem three: Does it? Can anyone here say they've seriously decided never to visit this place again because of one episode?
Problem four: See problem two's response. There is no such thing as having the image of a "decent TF community". It's an oxymoron. We're twisted perverts in the eyes of 99% of the internet.
Problem five: See problem one's response. We don't know if it will cause the site problems. Depends on where the site is hosted.
