To view who gave you their support in an MV Contest either with free or paid votes, go to the Contest tab and find your entry. Click the 3-dots on the entry and you should see the option for <Voter List>. You can also find your current contest entry from your profile under your portrait where it says "One free hand? Vote for me!".
To view voter lists from previously completed contests, you'll need a direct link to that contest's page. From there, find your entry and click the 3-dots as indicated above.
