The following sponsors gave me some decent ratios this year:
DukeDollars when Facial Abuse exploded onto the scene.
SexKey...always consistent.
EuroRevenue...great hardcore sites.
Several other NATS run sponsors have given me solid ratios of around 1:1000.
I have also earned a few dollars with SICCash recently so I must mention Brad Shaw`s established program.
Fire away with yours.
