How does Aimware's cheat for CS:GO fair up against VAC?

I've bought cheats for TF2 where VAC doesn't play quite such a big role as you can make a new account for free. I know that aimware is really good for CS:GO, but I know that it's also a big target for VAC. I would never think of cheating on my main account as I have a knife that I actually unboxed so I'm not risking my main. However, paying a total of £30 just to cheat in CS:GO and then to get banned does seem a bit annoying.

Also, if I use the same paypal account, as I use on my main, to buy CS:GO on my alt, will I get VAC banned across my accounts?
