Purposely exploiting a glitch even if you report it is against the rules. I'm sure one of the reps will see this though.

Have you considered the possibility he got all of these troops through drafting from all of these colonies? I find that the average strength of my colonies on na1 allows me to draft about 200 troops a day from each. With 300 colonies that's 60000 troops a day for him from drafting alone. And if he has alot of cities he could also be making hundreds of thousands daily as well.
