Same here! and same as Lisa, I also had a 90% acceptance rate with a port of some 2000 images, I stopped uploading 5 months back, no point. Also I agree, who you are is far more important then quality, if youre an exclusive you can upload almost any old rubbish and its accepted. Take 5 minutes and look at whats coming through as new images, just generics and tons of irrelevant material.
The quality will be held by Getty, the dustbin material by IS/TS.
