Hi – great question!
That is not directly supported, but it is possible to use Community Tickets to let organizers submit events with tickets – and split income received through ticket sales between that person and the site owner.
Our plugins are very flexible, though – so if you literally want to create some sort of paywall where users are charged a fee per submission that would certainly be possible through some custom dev work (while beyond what we can assist with, it should be a manageable task for most established WordPress developers).
I hope that helps and let me know if I can answer anything else 🙂
