Spam vooral afkomstig via Hotmail
80 procent van de email die door de Hotmail-spam-filters komt is en blijft spam. Per dag ontvangen hotmail-gebruikers collectief meer dan 1 miljard ongewenste emails.
"And it's increasing every day," said Parul Shah, a product manager with Microsoft Corp., which runs Hotmail. "Every time Hotmail or another e-mail service provider finds a way to detect spam, the spammer immediately has a way to get around that."
