If you've spent any time on here you know that no one actually clicks the links to read the article. Users need only trust the pages with an orange header.
I mean the upstream comment is basically saying don't trust clicking any links on the Internet--even on a site that presumably weeds out really dodgy stuff quickly. Indeed, not using the Internet is a solid, if rather extreme, security process to follow.
The thing about Reddit is that it has greater "discoverability" through search, profiles and algorithmic "hot" pages, so communities like that inevitably become swamped with low quality posts. There's a few niche subs that just degenerated into posting photos of purchases that arrived in the mail today instead of actually discussing the use of the tools.
