I completely agree.

Izolda has tried to attack me early game as well but failed at my defenses. He is the kind of guy that would have almost provoked a war between two alliances - just because he raided many weaker than him.

Though, it'd be insane to attack people much stronger than you or with an outlook on loosing the fight, in my opinion. But yes, farming active players much weaker than oneself is - is not okay.
