It would be very rare to have lived through an IT career and not make one or two fatal autopilot mistakes. In the 90s and early 00s it was very easy to lose a production system because you did something wrong that you did 1000x times right before. And this is a modern version of it; for me, this should not happen; if I designed GitHub, these people giving stars and watch would get selected based on the visibility of the profile. That hardly costs anything and then the user can just switch between visible and invisible at will and not lose anything. But I have made many similar mistakes in the past which is why I don’t delete stuff usually anymore; I just flag it deleted and gdpr material I encrypt. I simply don’t want either software bugs, hacks or human error to cause any damage. With the cost of storage and the fact that I work only in b2b, this comes at virtually no cost but with a lot of happiness for both our users and myself.
