It's also already more than a decade ago. But a friend of mine wanted to format a USB stick. So there was this tutorial online how to do it. I'm not sure if he copy&pasted it or typed the command himself. But anybody who used dd a lot, knows what happened, he damaged his root filesystem irreversibly by pointing to the wrong disk. I think repairing damaged filesystems with Norton suite or so was never a thing on Linux... ;) Long story short, even when typing well intended shell commands, you can damage your system. (Even on Windows or macOS!) Directly piping curl into bash shows a lot of trust. It's amazing how well-intended the web is, must be at least 99,999999% That said, I cannot count how many times following some tutorial blindly/some shell based installer made my carefully crafted *nix installation a bit worse. Nonetheless, most adware/spyware/malware I got through commercial download websites I think.
