the difference is:

3,2,2,2,2,2,1 (you press the button 7x)

1 (you press one button and your keyboard or another tool presses
3,2,2,2,2,2,1)


the first one is ok
the second one forces an account ban.

why?
because of a single rule:

One Keypress = One Cast per Charakter.
everything else = Bot process.
