Spam hour!

I am sick of this. First, today, I find a e-mail of spam in my inbox, left to me to mark it as spam as usual, two hours later, another two crops up: REPLY TO ME URGENTLY and CONGRATULATIONS!!!! WINNER. I now have at least 120 spam e-mails. And it's getting to the point now I'm about to close my account with the rubbish Yahoo team forever and create one from another mail internet site elsewhere!
