If you use the cracked version, you’re using cracked software. As has been pointed out.
It is available to be run in the specific version it was designed for, and if you have a license to run that version you don’t need the crack. In this case, you need the Cubase Pro License. You can be 100% certain that it’s not ‘cool’ with the the devs that you use it.
Facilitating distribution of cracked software here is also quite against the rules, and believe it or not, cause for banning. 
To be clear, the issue here is not that you want to run an old plugin, but that you don’t have a license for it.
Nice Youtube tuts, by the way. Some are also hilarious.
