I'm very wary of the photo feature, even cartoony and blurred out...will there be a bias between male vs female candidates in terms of whether people bid on them? Race? Hair color? Etc.
There's a reason most companies don't want you to attach a photo to your resume.
I'm not certain but from the copy it sounds like they'll be using that same pixelated cartoon no matter who the candidate is. Also, it doesn't appear like the signup form has a field to attach a photo.
