>I like the helmet and the sunglasses clauses

It came by experience with the use of a social dating site last year. We tried to find the best way, and short, as possible to have something in there to provide a sensibilisation so the site users would know that there wouldn't be any use to upload a hidden or a fake picture if they wish to use a dating site. As, the main attraction to a profile in such a site if the appearance and it has to be clean.

Here, it is different. However, in order to avoid situation close to that, such as expressed earlier today in this thread, we have to apply a minimum set of guidelines.
