im making bank from facebook traffic,

theres one particular page (not mine) that has 31k likers and about 6k "talking about this" it is niche specific and very busy, with a new posts every min,

but then there are other pages like the warcraft page for example, which has 2+million like but a user post only every hour or so.

is there a way to find super active pages with lots of people posting all the time?

The only thing I can think of is looking around on fiverr...
