I know somebody who started a SINGLE tumbler in late 2014. Today she has about 5000 followers and growing now by about 1000 per month... She works very hard at it and of course posts a bit of pictures from my site...
the reward is already felt, I get about ONE converted customer/day.
Now, why would anybody have many tumblers just to spam the same site ( or group of sites) ? In any business this would be called a Ponzi scheme.... But in porn is just the way to do business .... ??? a.k.a. In 60 pieces of shit maybe you find one undigested nut....Now, even if I was hungry I would not eat that nut because its still wrapped in shit
