Honestly, MySpace is dead at this point, and since that SpaceHey is a fan-made project (as a disclaimer on the footer), it unlikely they get sued or such, though I not aware of copyright standpoint in term of Germany.
I could give it a try in the future. There another Myspace Parody I discovered: https://myspace.windows93.net , give it a try.

I'm intrigued, I might have to check it out, myspace was great for music. Not sure about the legal ramifications of the copied code/assets though.

Aka-38caution pointed out there is a disclaimer. I guess that would protect them to some extent. I figure theyre right that copyright may be different in germany as well
