Basically you attack faster than humanly possible, the plugin detects this and tells the appropriate authority. You have triggered this on numerous occasions and filed up my page with annoying messages as you have apparently with Echo's. If there wasn't sufficient evidence to ban you, you wouldn't be banned. If you want to ever have a hope of being pardoned you need to be honest. I'm not saying that you are lying or telling the truth, merely that you haven't convinced me that you weren't hacking/fast click macroing/whatever the hell you were allegedly doing as there is sufficient evidence against you.
If I'm not convinced, others (admins) most likely will not be either.
