Um...he "multi-cheated," as in he played 2 accounts at the same time for well over a year.
That's cheating. It's not the worst multicheating we've ever seen, certainly, but it's still multicheating, and it's completely forbidden.
As a follow up: There is no "acceptable" level of cheating. If you resort to multiple accounts to extract some advantage, you have begun taking the game way too seriously. Maybe you're thinking of extreme circumstances. Like a war. Well, okay. You're at war. Lots of people are. If you're being beat by otherwise legitimate means (and statistically, you almost certainly are), you're being beat. Full stop. There is no legitimate reason to cheat.
