Modrinth currently has several forge builds published and has the tag for forge support, but as this is obviously not intended it would probably be good to remove those so people aren't downloading nonfunctional files.

Afaik there is no delete option I can use, so can't. Also yes these are Forge builds and it is intended that they have a Forge tag. They turned out to be so buggy that I marked them as broken, and currently have no plans to re-try making Forge builds.
