Hypothetical question

I've been trying to resolve this on my own but I'm stuck.

AI art used without permission. I've been dealing with this for about 6 weeks now and the situation isn't improving.

This involves software/code I developed over the past 24 months. I do not have documentation proving my ownership and timeline.

Do I have a strong case? What should my next steps be?

Illustrative response

I've dealt with this before.

The thing that gets people is escalating to a supervisor/manager. I'd recommend following the formal complaint procedure instead.
