Counter Strike Source Files

So I am making an ALT account on steam and I was wondering if I could use the files I already have for CSS on my ALT account so I don’t have to rebuy it.

Is there any way to do that?

There isn’t. Even if you would get the “brilliant idea” of copying and pasting the files over to your new accounts folders, the game would appear in your library, but it would be saying “Purchase” instead of “Play Now”

I’m just having this little hunch that you got banned for VAC or some crazy shit like that since you’re doing this.
