This seems reasonable to me, especially if it is personal use only. You make your own little area (subreddit? What do we call them now?) And have your bot post there. The odds of anybody else seeing it seem pretty low as nobody would even k ow about it but you and maybe the people running your instance.
Battlebit has been pretty much it for my limited dedicated gaming time. Super fun, easy to drop in and out of.
On my phone I’ve been working through the puzzle game Snakebird. Also very fun for when I only have 5 minutes or so.
