Some Yahoo Email Addresses Banned

Yahoo! Mail bans Allah and Dirty Harry handles
Yahoo! is banning the use of allah in email names - even if the letters are included within another name.
Other excerpts below:
Enquiries to Verizon revealed that a partnership with Yahoo! was to blame. Yahoo! will not accept any identies which include the letters "allah".
Nor will Yahoo! accept yahoo, osama or binladen. But it will accept god, messiah, jesus, jehova, buddah, satan and both priest and pedophile. Click Here
Confusion here with me, on satan and pedophile being allowed. In my opinion, these two are just as bad as the ones not allowed.
