  • Roll your mouse over event attendee lists to quickly discover how many people attending a particular event identify as dominant men, switch females, or any other age/sex/roles.

Frequently Asked Questions

  • Can the FetLife Spyscope show me X about a user?

Probably! If you’d like the Spyscope pop-up display to include more information about users than it currently does, I invite you to submit a feature request. The more requests for a particular type of information, the more likely I am to prioritize that feature request over others. :)
