A month ago I took advantage of the sale and purchased two additional battle chests and WoD expansions. Both accounts registered to same gmail account but with appended +account1@gmail and +account2@gmail -- Both have actually never been botted on and assumed them to be safe. Nope, just took about thirty minutes longer for them to get hit. I was still on the free time so I didn't have a sub, which is good, but the only trace to my other accounts is they were in the same guild with about 800 other legit players or who I believe are legit. I have a /21 of IPv4 space and use numerous open on tunnels (1 per account) and recycle them monthly. Too many assumptions I can make from this but they're trying to link accounts through numerous methods. Good game blizzard, good game.
