Thank you for chiming in. Facebook should add a new filter limiting the audience to users who have fewer likes. So for example he could advertise to folks who are interested in cats but have fewer than 5 overall likes.

How about another filter limiting the audience to users who have posted X number of entries to their timeline or the number of years they've been on Facebook?
