You can check to see who has selected your Art Profile at any time by logging in to your artselector account and clicking on the 'My selectors' link in the left hand navigation menu on the Network page. You will also find this menu on many other pages - including this help page - but it doesn't appear on profile pages.

In this menu you will also find a link called 'My selected'. Clicking this will show you all of your currently selected Art Profiles.
