It's curious that your #1 listed VPN NordVPN has a pretty tasty affiliate program but I can't see Mullvad (no affiliate program) on your front page at all in spite of it being most peoples' favorite ;-)

I tried to start a site similar to this one in the past. I gave up in the end because honesty and $$$ just wouldn't mix. No matter how hard I tried I couldn't square this circle. Economically I think it doesn't even work on a theoretical basis. The mullvad of most industries just wouldn't have affiliate programs whereas the scummy companies would have the best affiliate programs.
