Hello, this instance is linked in the Learning docs under Platforms using Frappe, Courses appears to have been compromised. I only tried their Login with Google option, but it redirects to a gambling/bet website.
The social media pages linked there seems to be inactive since 2024, and GitHub repo linked seems to be inactive since the end of 2023.
I believe this instance should be removed from the docs, and perhaps deactivated on Frappe Cloud.
