Quote - And while Daz do have a very hands off approach with the site, ultimely I believe that any failings of the site fall on my shoulders alone and I take full responsibility. 

Guarie, it's Daz's responsibility to get you some help, not to let you shoulder all the weight like this. :)
At least that's how I see it.
If you have to resort to manual approvals, then maybe they could see to it that you have a few more hands on deck to take care of things like that, to maintain the integrity of the site.
After all, it's in Daz's best interest to do this.

Believe me, I know what it's like to try and single-handedly run a big sales site, take care of orders, registrations, staff, problems, returns, the odd virus, newsletters, mailings.... It's a freaking nightmare and I don't envy you one dang bit.
