Down with manual ad approval!

Just a minor rant - I'm more than aggravated with the editorial review process used by some PPC engines.

While I can understand the perceived need, I can't understand the lack of trust assigned to established advertisers. After I get X number of ads manually approved why not set the account to "auto approve", then do some back checking or respond to reports of policy violations?

The dominate player in the industry, AdWords, will let ads run right away on the search network. If they can do it why can't/won't the other big players? I'm just amazed that at this point in the game there are still times when advertisers have to wait for days to get ads reviewed/approved. Honestly, I just don't see the need.
