Hi there!
My friends and I have been looking for a hosting site to use this Origins modpack, but haven't been able to find one that has the ability to host more than one person while still having this pack. We're all frequent users of Aternos, so we hoped that we would be able to use this pack on a site we were all familiar with.
It does seem to meet the requirements for the requests, including 10k+ downloads and server files, so I'm honestly surprised that it hasn't been suggested yet.
