Bad tankers and bad people

[Tyltyl]

I tanked only once, a year ago or something, for educational reasons =] And when I was tanking, I played in full force against all active (and strongest) teams of the League, there were just two or three of them. What's wrong about that? I didn't deliberately support one of them, I was equally against all of them. But against zombie-teams I tanked.
I see nothing unethical in this.

Total bull****, because if you are tanking you are losing points on purpose, except for the fact that you are giving points just to some teams you decide and your opponents don't know which ones. Not counting it is also a bait, because they see you playing bad formations, and maybe they can also forget to follow the game thinking it will be an easy 10-0 or make their reserves to play, while instead you give'em hell just because you think it's ok.
Not ethical, not fair and you just act like a loose cannon.

I didn't decide anything. They played against me exactly in the same manner they would play if I wasn't tanking. I played against all active and strong teams equally, no favourites. All who wanted to win the League, had to play against me.
What's the difference for them?
