Your personal Tumblr library awaits
"Wanna go ad-free" it constantly asks.
I'd paid a few bucks a month for a walled off, more adult section of Tumblr, then maybe, I might consider ad free.
Generally speaking, I seem to be middle of the road here and I find Tumblr to be quite prudish in it's idea of adult content.
There's money to be made. I originally type maid, French Maids in my mind. Ha.
