Welp, I reported a lot of AI prompt-injection bugs to various organizations, even some leading to RCE. They would say that they won't consider it as a bug, silently fix it and you are left there doing the work for free. I won't say "do not report stuff" but what's the point when companies are treating people like that, the incentive of finding and reporting bugs is literally zero nowadays.
Just post these on 4chan. That's the fastest way for the issues to get attention both good and bad and get a fix in as fast as possible.
