I feel you need to support the ladies that you enjoy. So yes, I buy memberships to sites. Haven't stepped foot in an adult store in ages though.
I read on Nina Mercedez's twitter page the other day about her giving some guys the riot act because the work one out to stolen content and then tweet her about it.
If you really like one particular lady then please support them by buying a membership. It's not like $20 a month will kill you, its the camgirls that will milk all the cash out of your pocket. :2 cents:
