Here's a thought.
What if there was a nice graphic saying something like "platonic cuddling = non-sexual" which everybody who wanted to could put in their photo set?
Many of the annoying clients do not read profiles. But they do look at photos. Such a graphic won't stop all of them, but it might stop or at least slow down some.
The repetition of finding it on many people's profiles would reinforce the message.
Just a thought. What do you think?
