A Calgary mom who started a group that's policing Facebook comments about dead teen Amanda Todd believes her sleuthing got one man fired from his job.

Christine Claveau says she got upset after reading a post by an Ontario man who wrote that the 15-year-old B.C. girl deserved to die.

Claveau says she clicked the link to the man's Facebook page and his employer, Mr. Big and Tall, was listed, so she contacted them and complained.

Dave McGregor, the president of Grafton-Fraser, which owns Mr. Big and Tall, confirms the man no longer works for the company.
