Since men with PA get to use "invisible ink" in open areas that only other gents with PA have, could there be a way of verified providers getting something similar. This is very helpful when an ISO is put out by a gent who is a known threat. In the past, the ladies have had to openly tell the other ladies to check the infoshare, which tips off the predator.
Invisible ink sounds like a great idea, but if it is invisible how do you see it? I have my body covered in tattoos using invisible ink. I hope no one can see them.
It was a cute little way of her meaning private tags. But really, it's an HTML tag so I don't think they could grant females the access and keep the guys and the girls from seeing each others. Still I think it would be doable with a little thought.
