Now-now it’s Reddit - he might have posted on one of the subs that people monitor with bots and silently autoban you from other subs for having ever participated in the offending sub. So he might very well have been Perma banned from 7 other subs for the comment, whether it was up voted, downvoted or totally ignored.
Flexible enough that Access Software built a library called RealSound that could do 6-bit PCM audio over it. Which isn’t great but is dramatically better than you’d expect. A bit over a dozen or so games used it.
I had one called Mean Streets that used it for things like voice. The game came with instructions for how to build a cable to connect your internal speaker to an RCA cable to run to a stereo or similar.
