Where can I find an engine similar to vktraget and sociate?

Question

CMS

Please tell me what ready-made solutions are there for creating a site where a user can create a task by likes, reposts, comments, and others will complete the task and earn? An analogue of the box, but for the social. networks like vktarget.

And also, are there ready-made solutions for exchanges selling advertising in social networks? networks as social?

If not, then please tell me where this can be professionally "manufactured"?
