For me spamm means, when some 1 is just stabbing you while he is not in a possition to stab you our try to stab you.
Like for instance, when you see him stabbing before you did anything then your first reaction is I cant be faster then him so I block. This is under condition as (normal stabs)
I understand when people know your style so they outhink you with being 1 stap infront of you. example when your opponent knows you are going to hold the next stab you just stab and take the risk that he will hold, if not you got to be lucky that he will poke you or miss you.
So again. Spamming for me is when people stab you while they are not even in a position to stab you, as we all got the same speed.
I know my english aint the best but at the same time I hope that you guys understand it
