Hi
LawrenceBowman .
We don't prohibit sharing links, but it is a little bit sensitive for links to downloads to be shared with no context. As I'm sure you know, downloads can sometimes hide viruses.
PlanetMinecraft and Curseforge are known to us all, but what is that site that you shared? How can we verify if it is safe? Are you affiliated with them?
If you post the link again, please provide more information first.
