I actually had the reverse problem: some stupid neighbor kept trying to pair something with my smart TV, to the point where I couldn’t watch TV at times, due to this moron’s insistence. I looked in the settings and also found I couldn’t disable Bluetooth, or blacklist devices, so I thought of a simple solution: changing the TV name to “virus”. From that day on, no one tried to pair anything with my TV.

There are service bots, that are used by many of the irc networks, that handle this within irc itself (nickserv, chanserv, etc…).

Obviously not, and I’m not even going into the depth of your definition of “everything”, where would a kid learn long division?

Here is a project that archived most of those games: https://flashpointarchive.org/downloads/
