The main reason I rarely buy from exo is this:

Does their biggest clients really have these limitations?
I mean a few examples here for min mobile banners bids:
Afghanistan, Albania, Algeria, Angola:: 5 cents CPC or 0.10 CPM
I mean given the quality of sites we have these days I wouldn't pay this even for US traffic!
WTF?
And on the publisher side I bet you can't even get 5% of these prices.
