How do I make ULX Groups Immune For Pinion ads?

Hi! So I have adverts from a website called Anyone that has a server/community on either TF2, CS, GMOD etc. can register. On GMOD it is a simple Lua Script.
I have a TTT server with ULX Admin Mod enabled. A player bought Super VIP, so I was wondering how to put them immune? I see in the config there is the thingy that I can put people immune. I did that, but it didn’t work for some reason. Can anyone help me?
