This is a macro that emulates pressing the space bar and is intended for use in CS:GO. It allows you to automatically perform a banihop - the ability to jump continuously without stopping. 

The advantage of this macro is that it is not detected by the VAC (Valve Anti-Cheat) system, that is, you will not get banned for using it. However, it is worth remembering that if a complaint is sent to you for using a banihop or suspicions arise, moderators can observe you, and if they confirm the use of a third-party script or software to perform a banihop, this may have negative consequences for you, up to account blocking.
