have you checked the Yahoo forum? Yahoo dont filter and sideline sites like Google does which allows the sites an opportunity of having their day some time in the future, they simply toss them away forever, banned for life.
You have to know that is the exception to the rule with Yahoo. I have been involved in lot of web sites and you can not possibly compare the scale of what Yahoo does to what Google does with their filtering since Florida. Google blocks sites whether they have commited a sin or not and they have virtually locked out mom-and-pop web sites completely with their massive filtering (Hilltop or whatever it is).
