Ashton. I thought the same. I work for a youth organisation, however, it's position alongside other said domains worried me.
Leave the cancer/advice sites etc to the experts and the relevant extensions, don't Market them alongside other domains. Especially IMO adult related domains.
I'm not one for political correctness/ morals are more important, and I am more than prepared to put my head up when it comes to safeguarding those who need it.
