Untrue.com

They have a simple goal: bringing together people who want to meet others for no-strings relationships. Not everyone there is attached - in fact many are single according to their profiles. Like Ashley Madison, activities on the site are kept discreet and clandestine.

Becoming a Member

Joining up requires completing a brief questionnaire and validating your email address. There's a section called "advanced profile" that lets you specify in detail your sexual tastes and fantasies. Be aware, the site has a strong adult theme and contains explicit images and content throughout. It also contains links to live webcam shows.
Free accounts are limited to viewing thumbnail size photos, and have no ability to send or open emails.

Staying Private

Members choose when and to whom they reveal information about themselves. Photos can be kept private and shown only to trusted persons by placing them in a private gallery (however this is only available to premium users).

Members can opt to have their identity and photos verified by the site's customer support. This, they claim will make your profile ad stand-out from the crowd, and will show others you are genuine and your details are authentic. Verified profiles also display a certified badge.

Searching

The advanced search is only available to paying members. Free users must make do with a simple search form that lets you find members by distance, gender and who they are seeking. A useful option lets you restrict searches to verified photos only. However this will restrict the number of results you see as it seems few people there have gone to the trouble of getting verified.

Briefly...

Untrue is an explicit site for those looking for casual, no-strings relationships. It doesn't have classy, up-market feel as Ashley Madison - the sexual ads do become an annoyance very quickly.
