One gigabyte of storage is bigger than a lot of disks they sell in brand NEW home computers. They also sometimes get LOTS of domains, to make your job even harder. Spam of all sorts is an ever-increasing problem. Back when I started on the net, in 1991, you didn't hear of spamming. Today, it's 1996, and I have a news account with Airnews.
Email spam is even worse.
America Online has had to sue to be able to institute spam blocking, and they and four other sites providing Internet email are suing Cyberpromo to make them stop forging addresses. It's gotten to the point where people are actually lobbying Congress to include email in the laws that prohibit junk faxes. Don't support businesses that spam, don't support sites that don't care if their users spam. It's up to all of us. Boycott Internet spam.
