Honestly, this is pretty much what LLMs and user generators were built for. A couple of the shit post subs (anything with horny on main) already have tooling set up.
For the crowd, the goal is to clog the system in a way that is really hard to filter. You want bad data and also lots of differing types of bad data. Spam shrek, bee movie transcripts, AI generated rants, report a guy called “Lehuge” 80 times with conflicting info, etc. You know the drill.
oh but don’t forget clipping and the fact that you now increased audio variance means the 10¢ tinny speakers at checkout cant power it, so now you have to work around perceptive loudness and normalize to speech frequencies and when you get to the shop to install new firmware you see a granny wearing glasses asking “what does the self checkout menu say?” and now you have a new problem.
