Give it a shot! There is a macro setting but i dont know how to use it :v
you just click the spam key and you just hold your shoot button and then you bind it to your shoot button or whatever you want. and make it like activated on press or something like that. or look it up on youtube
It's not using any changes in the game, it's just modifying and outside source(in this case your mouse) so no you should not be banned for it(the only way is if players report you in-game for obvious hacking or something like that, but i assume you already know that lol).
