We feel the same way regarding the need for discretion, and crop all our photos so our faces are not visible. Should a connection show promise, we will, after careful consideration, share face pics from an outside e-mail address that does NOT contain our lifestyle site username. These pictures are never "uncropped" images of cropped ones posted on our lifestyle site profiles. They are separate images that we only send for the purposes of sharing face pictures. How's that for "paranoia"?!?
Some folks will just not respect your wishes and concerns regarding this topic, and they will likely be folks who you wouldn't click with anyways. In our opinion, you never need to apologize for doing what you feel is right regarding your own safety, discretion and comfort.
