They are rejecting people because they are stress testing certain aspects of their system. They don't want a ton of total volume. They want specific loads of specific volume for specific amounts of time on certain subjects. This is the same reason Google did not give everyone on Earth a Gmail account at once. They offered more storage than MSN offered with hotmail, so then Microsoft said yeah... We can match anything they offer for our 10 million subscribers. Then after Google knew they could handle the volume, they increased the storage for Gmail accounts 10 fold. MSN couldn't do that. Keep applying and hang in there. Yahoo is not stupid, and even Google admits they will lose publishers to competitors who are paying big money to get a foothold in the market place. Keep applying.
I hear payouts are much smaller then they were 6 months ago? Also, I only applied for 1 of my sites. I got rejected for that one site; does this mean I am rejected for all of my sites? Should I re-apply?
