The Internet world is giving the Toronto Maple Leafs more grief.

Leaf president and general manager Brian Burke is the wounded party this time, as someone has been impersonating him on Twitter, a social-networking and mini-blogging service. Twitter allows its users to send and read short posts, functioning as a message board for those who think, for some unfathomable reason, their random thoughts need to be inflicted on others.

Someone signed up with Twitter under Burke's name and posted a number of remarks insulting to other people in the hockey world. Burke said in an e-mail message on Sunday night that he had nothing to do with the messages and the Leafs have issued a complaint to Twitter about the imposter.
