Yep, also back in the day it was common protocol to have .history files chmod'd to 600 by default.
Having an unlimited history is great. Sometimes there'd be a tool or resource I'd vaguely remember skimming (e.g., "oh yeah, I was working on ___, so it must have been on (day +/- 24 hours)". I'd find a command that more or less is chronologically synced with the command, then go into Chrome's SQLite history db in my User Profile to find it.
That wasn't necessary. You could easily have made the very same point without calling someone's personal pastime/hobby, "garbage".
It's one thing to use porn as an example of "things that may be awkward if found in my bash history", it's something else to get judgemental about it. Unnecessary and off-topic.
