Flow - We detected unusual activity

Hello, first of all, have the rules changed? Previously, regardless of whether it was an image or a video, we could submit 5 or 6 requests consecutively; after that, it wouldn’t allow us to submit any more requests. Now, even if I submit a general request, wait for it to be created, and then submit a new request, it says “unusual activity detected” and doesn’t produce anything. This happens with both images and videos, and I’m having problems because it happens so often. My membership expires before I can even use my credits. Even if I use the highest ultra package, I can’t benefit from the flow. I want to know if this is a situation specific to my account or a general issue. Please investigate this matter and determine if there is a problem with my account. I urgently request a solution to this problem.
