I dont think thats gonna happen .. the only way to not get a server ranked(rating enabled) is Pb off .. or XP value modified .
I dont know what is the problem if servers allow the option FF on / off or not.

This is a tracker , and many changed have been made for rating , if you exclude more than half of servers ... its not gonna work.
If you dont like Wood server or FA just dont go there and find some servers which allow FF.
thats all i can say.
