If your ISP has to upgrade their systems in order to cope with increased spam traffic, then the costs will be passed on in some way to you the user.

Many spammers advocate the use of opt-out lists.
This means that if you don't wish to receive Spam from a particular source you can have your details put on the opt-out list and you will receive no more spam from that source. Do you really want to respond to thousands of opt-out lists asking for your name to be removed. If you do want to receive information from a particular organisation or types of organisation, then you should have to subscribe to an opt-in list. Even the use of these devices may not be without problems. It is necessary to have some check in place to ensure that your name has not been registered by someone else either maliciously or as a 'joke'.
