Greek,
The only way we can win is 2 ways:
1) Report spam, and have someting done about it. However, this
puts a major dependency on search engine cooperation. We cannot
do it from reporting alone.
2) We resort to cheating better than the cheats.
I personally could never do # 2, but this inevitably will be resorted to by some – “if they get away with it, why not me ?” syndrome.
I truly believe it is a lost cause.
