If you are not getting trolled it doesn't mean it doesn't happen to anybody else. Hiding behind what "doesn't happen to you" won't solve anything and not only in this game. Many people aren't affected by many other problems in life, does that mean that the problem doesn't exist?
Trolling results didn't happen to me for some seasons, but in the latest one I've seen streaks of weird results for me, for association mates and for many other people on the forums. Every time you see the same stuff, manager absent, bots playing, shot efficiency higher than usual.
You can keep comparing this to reality which is just silly, much like comparing any other manager games based on math to what happens in reality. There would still be shady stuff going on, bugs, problems and a lot of other stuff.
