Nudity getting out of hand, more profiles showing up with bare asses, penis's, users are just using colored lines drawn over photos as camouflage.... really, Sure GRINDER is about Sexual Activity, but upfront nudity cheapens the site, ad a PRIVATE PHOTO option the user can UNLOCK for approved viewers, its done on other sites, can't be that Difficult to develope and install.... Make it a premium feature, make GRINDR some money.... Besides, you can send NUDES through the messages....
