I don't understand why isn't banned. They're spamming unsolicited emails and are trying to make a mockery of the trust system. How is all that not grounds for a ban?
Looks like the "emails" is a typo.

IIRC, only theymos can read the PMs.
But if you click "report to admin" after receiving an unsolicited PM, the global mods will be able to read it, and banned the sender if needed.
So, I guess the receivers haven't reported it yet.

Yeah, it was a typo. I was referring to the PM's, thanks for the catch. Looking back at that post, I made a few errors. Guess that's what happens with late night posting and a few beers, LOL!
