You asked SE if you could get in touch with the owner of that character? You know that they'd say no on every level, right?

If you didn't get the name you wanted, you'll just have to grin and bear it, elongate it, add a ' mark to it. But if you use a name that's 'popular' in any sense, you may night get to use it.

Heck, in Runescape (Lawl runescape) when I played I was addicted to Naruto, and I was beyond upset I couldn't pick 'Garra' as my name, and had to make due with Garra98765.
