terrible mastodev ideas please do not take this seriously
@KS I can actually think of a legitimate use case for this, with two caveats.
#1: It can only target your own instance #2: Only administrators can do it
This way, if an instance admin needs to get an urgent notice out, all users can receive it without worrying about whether everyone's following that admin, or paying attention to the local timeline.
@KS complementary bot that receives @everyone@instance messages and forwards them to every other instance that it's aware of
and the bot runs on multiple instances so eventually it creates the most obnoxious feedback loop of all time
