ye that can happen quite often. that's when you are lagging and can hit your opponent as long as you want until the lag is gone and the console then thinks that you were using kilaura or bunnyhop. That happened to me like 60 day ago on hypixel and I got banned for a year xd. I am still waiting...
I mean ur right but there are special mouses that have 2 different modes, the one is that it is normal holding down left click and the other mode is that the mouse clicks while you hold down left click and I think the second mode is forbidden cuz I got banned like 3 hours before for 24 hours...
