Monetization. Classmates again "burn" :)

On classmates appeared banner "Remove a bad grade." I became very interested and clicked, but at the same time I thought, “Finally, they have introduced something new, we must try.” The page opens, I see "New paid service from classmates."
Wow! The gentlemen from Odnoklassniki LLC are again going to benefit from the originally unfinished features.
It is very interesting to bring such ways to make money on users.
I am not at all against the suggestion to users of additional benefits for the additional reward, but some painfully dubious methods in the 1st social. Runet networks (by attendance).
In any case, there will be those who will use it, the only question is the number of such users.
