Questions about scpsl hack

I understand i have to go to the telegram to buy it, but there is some questions i have about the cheat. If i inject it, do i have to get a spoofer? Does the cheat get detected often? Will certain servers know if i have a cheat injected? If i play legit wit the cheat, will i still get banned quickly? Is it easy to inject, and do i have to change certain properties on my computer(i hope not). If you can give me the basics, that'll be great
