the REAL greytomorrow, Part II

I discovered on YouTube, there's a user who's going by the name of greytomorrow. No, it's not me. My page is here. What do i do? Do i contact this (at the time of this writing) 21-year-old male from the UK telling him that's my name and trademark since 1980? The rub is that this "greytomorrow" account was created only two months ago! My bad?
