Delayed approval for photos

How many photos do you have? They review the best seller accounts first and then move on to accounts that sell less, like mine. A friend of mine, his account is one of the best seller accounts, and he told me today that his photos are reviewed every day, literally every day. His account has around 10,000 photos, so they get reviewed quickly. I think this is unfair. Those with fewer photos have to wait longer for approval. The question is how long they have to wait to have a large number of photos approved to get faster sales. But their photos are delayed too long for approval. Fewer approved photos mean fewer sales, while faster approval leads to more sales. My account took a year for all my photos to be reviewed, and that was just completed a few days ago. One year!! of waiting for approval. It's really unfair for me.
