No offense taken.
Just think that whenever You say "It's buisness" someone can add that "We all make mistakes" which goes both to You and those frauding russian webmasters.
Because they just get themself out of the program because of what they do.
You on the other hand simply loose market.
I for example dont really dislike any Russian Webmasters banning at all.
Why?
I beleive that Your result of Your work is exactly what You should get for how much and how good You work (pretty simple eh?
).
But if working with Russians is a hard job for a certain company than some other company with less requirements will make a dollar out of it (as they already do).
That simple.
