Well, it would be almost impossible to track what you're doing, unless they look at your IS Boxer configuration file.

In IS Boxer, we send one keybind on key stroke down.
And a different keybind on key stroke up.
The game receives two different keybinds, not our one key.
Our down/up speed will vary slightly.

The same as if you had one finger on F12 and the other on 1.
And were spamming both of them.

If you're uncomfortable with this, as stated previously -- remove the keystroke down or up command.
And just spam the single key, at roughly twice the speed you were doing so before.
