You won't receive an in-game mail from someone you have on ignore. However, the making and deleting of alts for someone as intent, as this guy sounds, on ruining your day, is pretty easy. I heard there might be something in the works to combat this by ignoring the battle.net account of anyone you have on ignore? Or was that a request? In any case, it's a brilliant idea.

I've never paid for a COD I didn't intend to, but if you're a bit tired and used to the usual click open, click take, click accept, then I could see it happening. Hopefully, he placed the price well above anything people had on their toons at the time.

As for the website. We had an issue in our guild about a year ago where a couple caused havoc and with half truths, bad language and just a lot of energy for drama, split the guild in half. They used the website as a means to communicate with people initially. While we could block them, we soon realized that our website owner was on an extended break. We couldn't get a hold of her strait away so we contacted the website service providers. They were very strict and clear that only the owner could make any changes, despite her being absent for several months. We were also unable to delete the website and start a new one with the same provider as only the owner could do this and they didn't support sites with the same guild names on the same servers. We did get in contact with her eventually and had the website ownership given to an active officer.

My advice regarding this whole thing would be report report report, he will eventually be taken care of in-game. Start a new website, delete your bookmarks to the old one and never look back. Making a fresh start will lift everyone's spirits and prevent this individual from making your lives difficult in the future.

Good luck!
