I assume you want to host your private code, because Dockerhub is actually free (for public images, of course)
If you have a VM somewhere (say, AWS) you can run your own Registry (Dockerhub is essentially a Registry): docs.docker.com/registry/deploying/
If you are attempting to use it for production, I'd suggest implementing SSL with Let's Encrypt from the get-go. Also, for management, I still have to try out Portus: port.us.org/ (ACL, namespaces, storage management, etc.) It seems pretty cool, for a free alternative to Docker's enterprise offering.
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.
