Spammers not work anymore??

So when I was ingame with my friend, I decided I want to spam,
but when I pressed the hotkey (F11), nothing happened

So I kept pressing it, and still nothing happened

So I pressed enter, so all the spammer had to do this time was send the message,
but still, nothing.

So when I went out of game, I decided to test my spammer on notepad and it worked fine.

What do you think it is?
Nexon finally patched spammers?
or Nexon patched hotkeys
etc??

Hmmm maybe the spammer only don't work for you but the other answer is maybe the nexon patched the hotkeys i relly don't know
