This macro is a banihop for the CS: GO game and is not detectable by the VAC system. However, it should be remembered that frequent use of this macro may attract the attention of other players who may file a complaint against you. As a rule, in such cases, the administration reviews the records of matches and may decide on a violation of the rules, in particular on the use of third-party software. 

The work of this script is based on the space key clamp (space), while the macro does so that the jump is stuck, which allows you to achieve the banihop effect.
Installing the macro is quite simple: you just need to bind this macro to a key that is convenient for you.
