How much would you pay Facebook a month to have an ad-free experience?

This question opens an inner fight ':D As a marketer I can say that FB ads can be very important, but a user - I am annoyed by them XD FB should invent some less annoying system that can satisfy both sides.... But would I pay for it... hmmm... not sure, it pretty much depends on how much time I am (or I must) spend on that platform...
