Steam account thieves?

Is there a section that covers Steam account hijackers? I get sometimes as many as 25 emails a day claiming to be Steam or Steam Support saying login attempt from a new address. I never click on them and they all go to my spam mailbox. But would like to see something done to these thieves who try to steal people’s Steam accounts. I am sure they are related to part of the gift card frauds. They hijack accounts looking for money in the users Steam Wallet, then buy something as a gift for themselves.
