This thread focuses on an undesirable side of Linux:
Bad Guides on the Internet.
Some have useless information, some have outdated information and some have dangerous information. There are even some that harvest information.
Please post sites, guides, threads, etc. you find that are a "Bad Guide" to help others users know which to avoid.
I will begin with: https://tutorialforlinux.com/
A generic beginning rather than a particular page... This site is pretty much useless in every way.
Fake Guide:
I left a comment warning users that this guide will break Zorin OS, not upgrade it and the Site Administrator deleted the comment.
