50SHADES.NET would not bring you a TM issue unless you use it the wrong way. Then again doesnt really make much sense, so I would just learn and toss. The others just throw Learn and Toss.
I just saw the UK extension of NIKESHOES on sale on sedo. Just wondering doesn't sedo have any trademark check in place before putting an domain out for sale ?
Well we don't unfortunately provide information regarding trademarks as we say when someone lists a domain name for sale on our marketplace that they are representing that they are the legal owner of the domain and that the domain is free of any legal proceedings challenging your right to use the domain. We don't provide any legal advice but maybe you can find more information here: xxxxxxx
