What is SMARTYs ruling on torrenting?

Just a query as I wasn't really able to find an answer online. Does anyone know how SMARTY views torrenting things? Since they don't throttle usage or anything. Is there ever a scenario they'd revoke access/account for things like that?

I do consider a VPN and I know it works as a few years ago I used a VPN torrenting on 4G. Just figuring, if their policy states not to do certain activities such as torrenting or not or if they act on it.
