two webcams that never failed me since almost 8 years:
CamDough and
Interdollars i know they are generally in Asian niche but you asked for honest, always paying sponsors - here you got two. i've tried 4-5 different always fails me, like my traffic wasn't counted (4 uniques from banner spot which usually sends 200? a joke..) or many traffic send for zero income etc.. but again it maybe cuz i'm sitting in Asian niche and in this very nich Camdough and Interdollars have no competition.
anyway good luck with any cam site you will try, hope it will work for you better.
