I was trying out some sabotaging to see if any of the errors are predictable. The quantity on the left of the arrow is what I was trying to sabotage. The quantity on the right of the arrow is what it said I was trying to sabotage. Whenever I got an error something different was attempted then what I was trying. (Neutral) means I wasn't caught but I didn't succeed in sabotaging. I can't notice any pattern for the errors. Perhaps the errors are cased by two threads trying to write to the database at the same time or something weird like that.

Hey...keep your grubby little paws off...
heres a spy tip unless your ranked 1-5

not much of a garuntee that you will be successful due to the fact you will be spending a lot of resources just to boost your spies up

Not really...you can sit there doing -nothing- but train your spies. You'll go down in rank reaaaaallly fast, but you'll still stand a very good chance of sabbing people.
