There's a lot of questionable methodology and straight up larping in these communities. Sure you can probably make Opus hallucinate a crystal meth or bomb making recipe if you get it in a roleplaying mood but that's a far cry from actual prompt injection in live workflows.

Anecdotally i've been experimenting on those AI robocallers that have been spamming my phone and even on the shitty models they use it is non trivial to get them to deviate from their script. I hope i can get it done though, as it would allow me to hold them on the line potentially for hours doing bullshit tasks, and costing hundreds to their operator.
