I'm inclined to wonder if the freepage sites realy do have the infinite disk space, network connectivity, and processing abilities that botnets do. Sending an email is a fairly minor operation, expecially if you put multiple recipients on the envelope. But if the botnets are making a new spam page for each spam sent, then are doing probably 10x or more the work they would do to simply send a spam, and then they still ahve to send the spam. So it cuts their productivity by a factor of 11 or so. I pick that 10x number based on the idea that it is probably a multi-step transaction to register for and create a new page on a freepage site. And that assumes that there is no error in making the page due to a name collision or some such. Of course the freepage sites could probably completely stop this practice simply by putting a 10 second delay in the middle of the page grabbing process. That would slow spammers down to 6 spams a minute per botnet process if they are not reusing pages. (Assuming 1KB per page with no graphics and a small botnet able to send 100K new page transactions per second, the disk space on the server will disappear at the rate of 100MB/second. If we assume a page is more like 35KB since it has some graphics, the server disk space will be disappearing at 3.5GB/second. Admittedly disks these days are around 350GB per each, but you would think a freepage owner would notice that he had to order a thousand new disk drives every day to keep up with new account usage.) ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
