No and never would do it.
The wife and I have posted pictures over the years on various amateur or swinger ads sites, but on every one we have edited out any with full face. The only exception has been the private ones we have sent to couples when we have moved past the preliminary contact phase and meeting in person is a real possibility. Even then there was uneasiness as several times we never heard from them again after doing so and while they may have just been that we didn't meet whatever superficial criteria they were seeking; but it could have also been nefarious and who knows where those pics ended up at. The only saving grace was the fact any face pics we did share where not nude.
So while it's an individual decision, but I agree with a lot of the posters here in that it's likely never a good idea. There have been several members here who have had their pictures copied to other websites without their permission, so the less way to positively identify someone the better. If anyone wants to show their face it's better to separately post nudes with no face and then face but fully clothed to lessen a direct connection between the two.
