I get more spam in my comcast email than my yahoo, gmail combined, and I have never used it for any commercial purpose. In fact, only 1 person even knows it besides me and comcast, and she hasn't sent me an ecard or anything. They deny making it available, tell me I have to add every spam email directly to a blocked email filter and that they "don't have the technology" to block spam, even though a Luddite living in Botswana has access to that technology. Looks like I'm switching to AT&T, although i will miss the speed
