Social network for the distribution of invites

In the light of the popularity of invitations to these or other services, there is often a problem: you want to invite, and there is no one to ask for. Or vice versa - there are many invites, but there is no one to call for service.

The natural way out is a social network for distributing invites. At the same time, the services will be advertised (“I have 50 invitations to yDaFcku” - “What is this?” - “Oh, be it unearthly!”). It is possible to take some APIs of social networks and simply bolt the necessary functionality to it.
