The prices for services compared to other similar platforms are at an average level, and in some cases even higher. However, the administration behaves quite arrogantly and doesn't hide it, as the commission is 50%. For me, as a performer, this isn't too critical since I earn an average income, but advertisers pay more here than on other platforms, so there aren't many new tasks. Additionally, the rewards are cleverly tied to the rating. The formula is as follows: the task amount is multiplied by the square of the rating divided by 10,000. So, with a 90% rating, which is an excellent indicator, I receive the task amount multiplied by 0.81. This makes it difficult for newcomers, as they earn 5-7 times less for the same tasks. There is also a convenient filter that allows you to exclude tasks by themes and platforms that don't interest you, and the number of platforms is impressive: besides VK, OK, FB, and Twitter, there are also LiveJournal, Mail, and Google+. Overall, there's plenty to choose from. I earn about 8-10 thousand a month, working no more than 2-3 hours a day, so I have no complaints.
