So I'm assuming someone bought this and redirected it to Bing as a joke.
iirc, someone said it was owned by Microsoft.
uughhh I want to believe
http://whois.icann.org/en/lookup?name=abc.wtf does not indicate that Microsoft Corporation, the organization which operates other Microsoft domains, operates abc.wtf
Maybe this passes as humor for some folks?
Haha yes this is a joke.
