If you were a mod that had to deal with the threat of it in the past you should’ve heard it by now. Or if you read news about FB or whatever else having to remove it, it tends to pop up in those articles too.
I hadn’t heard it until I was on /r/ModCoord and because there are so many power mods there with tens of millions of subscribers that term popped up a lot.
I wouldn’t say it’s lucky, there are tons of jobs that require & presume you to have the most basic knowledge about filesystem or folder hierarchy and the young hires I’ve had in the last few years act like I’m throwing them into an advanced calculus class. Mouths agape and eyebrows scrunched up as I slowly show them where files go, like I’ve invented fire in front of their eyes.
