Question about VAC ban

Couple of years ago I had an account with CS:S, I played for sometime and then gave it to my friends because I didn't give a damn about it anymore.
So .. now I feel like playing Gary's Mod ~ and I see it needs a Source game to work. So my question is, will I be able to play Gary's mod online with a vac banned CS:S or I'll have to buy a new CS:S ? anyone ?

I'm VAC banned from CS:S but gmod still works perfectly fine for me.

Vac bans arn't active in GMOD so ya

See what VAC banned your games and then see if it is garry's mod, IF not then you can play
