To be clear, my comments were pointing out that what's described was not criminal. I didn't take a position on what's ethical or not.

That said, I think helping VPNs is a good thing ethically. If he'd been arrested for running a Tor node that was used to download child pornography (which has happened), I suspect most people here would defend him.

Helping spammers is bad, but, at least as described by OP, not illegal.
