Apparently, padding one's score through cooperative vulching is considered cheating. At least, it is when we're involved. We just vulched each other, and openly admitted it, no second accounts needed, which got us 2 members banned outright for "attempting to cheat".
If exploiting the trial account system, or starting a second account simply to harass, annoy, and pad scores isn't considered "attempting to cheat", then there's a seriously skewed double standard here.
