Is the great AI art experiment over?

I had the same 35 not accepted and I think that was the whole batch, mostly just tagged quality issue, was a bit strange as I only get the occasional not accepted. They weren't any different in quality to others previously posted.

Without seeing a picture with the refusal reason, we can only speculate. Pictures that are in good quality get accepted.

Were your rejected AI submissions titled & keyworded as AI generated?  I ask because the recent AI guidelines may not have been in place when you first submitted.

In my experience, AI often gets things wrong.  We've seen some badly botched AI caused by synthesis errors.  Faults ranging from 5 legged horses to munged hands, legs, eyes, webbed feet, too many fingers/toes, partial artist signatures, etc...  

Were your submissions high quality upscales with good details and crisp edges?  As @Jill_C  said, we would need to see the rejected full size image to comment further.

to be fair, i always expect 1 or 2 from a batch this large to be rejected, even if it's just for being derivative of others in the batch. but to have such a large batch rejected out of hand when the images were all varied (some AI, some not; some illustrations, some faux-photos) is just very weird and seems completely arbitrary, especially when a larger (and not as good) batch was 100% approved a day earlier.

If you upload a few samples here, the community members will review and provide feedback. Every rejected AI image we've seen here has obvious issues.
