I received one of those letters also for adidas jerseys. I don't know how they got my home address which made me suspicious. I voluntarily quit all sales as soon as ebay advised me too. I had only sold 3 jerseys when I got the first email from adidas counsel. Scared me to death. I have no proof that they are even counsel to adidas other than their email.
I think I will wait and see.
