We have 3 feeds that we use normally, but I will only comment on the first 2. Our primary feed is Yahoo, if for any reason they do not accept the domain or the traffic we send the traffic to our secondary provider which is Ask. The reasons could be that Yahoo thinks it's a TM, they have their head up their a**, Yahoo could be down, they think you are in a country they don't accept traffic from, or they think it's a controversial domain. Controversial is where you have something like an adult domain with teen or girl in it, controversial is basically the idea of having 2 concepts combined that they think are bad. Our Ask feed requires us to send your traffic to either meanwhile.com or mustangranch.com. Meanwhile.com is non-adult and mustangranch.com is adult.
But if you want to send me the domain, I can tell you want Yahoo says about it. In some cases Yahoo doesn get it wrong and we can get them to correct it.

Across the board about 28% of all initial page views are 1 click domains with Parked.com. Yahoo our primary provider tells us what is a 1 click versus 2 click. There is no flag to make domains go to a 1 click with us or any Yahoo based parking program.
I could go on for days on whether a 1 click or a 2 click domain makes more money. And at the end of those days, none of us would have learned anything.

But I can tell you one thing that always makes sense, one click domains have a lower smart pricing score/traffic quality score than a 2 click domain.
