Yep but as you see these people selling on ebay for $$$$$$$$$$$ have no intention to sell it for real as anyway nobody will buy but I think it's for for them to make them famous and some domains were in articles on serious national and international newspaper, this is free advertising for them.
I do own a mj domain but not about his death or anything immoral, I like his music and wanted to have a domain as a MJ collector so I reg mickael jackson albums dot info where I will build a personal website, of course if family of MJ have filled Trade mark on mj names, I'll just drop it. I think they should control his image (trademark, copyright) as soon as possible because I see people using his image (tshirts, websites, other stuff) without givingany royalty fees to MJ families and they do whatever they want that can also be immoral. I saw a tv report months ago about marylin monroe and they have a army of lawyers that track all product, you won't find 1 product on the market that was not been authorized by marilyn monroe lawyers and owner of his mark. Everyone use her name, image... must pay royalties. MJ is loosing big big money since his death with illegal side products.
