Hey Droopy. Are you working at Adobe ?? let me know so I know if it is going to actually help with the situation.
How can you help me if I share that with you. Firefly did not specify the exact words that is in violation to the adobe guidelines. This is terrible experience. Why would I pay $$$ per month for something this terrible?
Probably the best source is these forums where people said their prompt was blocked, we asked them for their prompt, they told us, and then we told them what words triggered it. There is no other published documentation.
