I decided to try the crowd service on VKontakte. It was in waiting status for several days, and I received an email about transferring it to partners. However, after 3 weeks, I received no information. The question is, how can one control their work? There were no clarifying questions, no briefs, no approvals, and no communication at all. What can be promoted without the client's oversight? Miralix support replied that I specified the domain, and in their opinion, that is minimally acceptable. They also noted that I could have left a comment. But no service should be provided this way. What kind of statistics can be gathered? In 3 weeks, there were only 9 clicks according to VK metrics. Money has just been thrown to the wind. I do not recommend it to anyone.
