So lets model the various scenarios that may apply.

1. just delete it

    (cost to receive spam) + (time to press delete)

    eg for 1 unsolicited email and 6 million recipients
       (6million*R0.00613) and (6million*1 second)
        = R36780 avg bandwidth charges and 69.44 days in sequential seconds
       or
        = R36780 avg bandwidth charges and 1'ish semi-parallel second

2. add to filters (manually or with levels of automation), then delete

    (time adding to filters) + (costs from 1.)

3. Report, filter, delete

    (time reporting spam to one or more entities) + (costs from 2.)

4. Unsubscribe, report, filter, delete

    (unsubscribe x number spam received, possibly with screenshots) +
    (costs from 3.)

5. complain on repeat spam after unsubscribe, report, filter, delete,

    (time spent lodging a complaint) + (costs from 4.)

6. Add yourself to a DNC list, get spam, unsubscribe, report, filter, delete

    (time adding addresses/numbers to 3rd party list) + (costs from 4.)

7. Buy an antispam solution, get false positives, lose a sale

   (cost of antispam) + (time spent diagnosing the problem) + (lost sale)

Any other models that apply?

How do we measure the cost of a person's time?
- do we use minimum wage?
- how do courts value a citizen's time? does it vary between say a doctor
  and a ward of the state?

How do we measure the cost of bandwidth?
- do we use what a consumer pays for 10mb increments of mobile data?
- do we use what TENET pays to Seacom to service a massive network?
- or the average/median cost to the consumer?

How do we measure the actual cost of spam in bandwidth?
- do we use average size * determined b/w cost?
- do we use overall size * determined b/w cost?

How do we cost antispam solutions?
- some are free, except for some time (eg spamassassin)
- others cost money

So far we have my proposed costs for part of item 1, and a rough estimate of
how long it takes to press delete. The rest is awfully complicated.
