Video hosting for starters. That will increase interest in the front end.
I also think that running google ads in places like Xvideos, pornhub and other similar sites will drive traffic upwards in Dporn, especially when peoeple realise that they could earn from their content.
Finally, perhaps you could also take the onlyfans model and then make it a bit more crypto friendly by creating a portal where people make verified accounts and then give these verified accounts the freedom to have private sessions and content for paying customers. Customers can pay with hive, porn, and any other token of choice. Through this move, you will have created a very good use case for crypto through porn.
