Found the error Not allowed to load local resource: file:///etc/passwd
while looking at infosec.pub’s communities page. There’s a community called “ignore me” that adds a few image tags trying to steal your passwd file.

I doubt this person ever expected anyone to find it or to read that much into it lol
