Punters who worry about this may as well quit punting.

Besides the date stamp on a certificate, a WG should insist on seeing a Punters ID document as well to verify his STD certificate. Like has been said above, a fake certificate can be printed out.

Veronica makes a valid point, there are many punters trying to push their luck or even becoming forceful.

Interestingly the big scandal a few years ago where a punter came crying that a wg who he trusted enough to go bare gave him the herp. And he ended up passing on the herpes to his fiance and ended up ruining his life. The WG involved is still in the business as is the punter who presumaby is still punting since he occasionally posts on profiles and the forum.
