This is another example of moral-outrage eating itself.
My 7-year old daughter has an arm full of them. Bought them from the local shop. As have all her friends. They just like them because they are "colourful fashion bracelets".
Then along come some website, The Sun, and MPs, and tell kids "no! they are not fashion! they are sex-toys. Here, if you go to www.whatever.com, you can read the rules and find out how to do it! Which, of course, you shouldn't! Outrageous!"
If everyone had kept schum, then they would continue to be... harmless colourful bracelets. It's the GROWNUPS (so-called) that are turning them into something more.
