Another factor that would mitigate spam if POW tokens have value:
|
|
|
|
|
there would be a profit motive for people to set up massive
|
|
|
|
|
quantities of fake e-mail accounts to harvest POW tokens from
|
|
|
|
|
spam. They'd essentially be reverse-spamming the spammers with
|
|
|
|
|
automated mailboxes that collect their POW and don't read the
|
|
|
|
|
message. The ratio of fake mailboxes to real people could become
|
|
|
|
|
too high for spam to be cost effective.
|
|
|
|
|
|
|
|
|
|
The process has the potential to establish the POW token's value
|
|
|
|
|
in the first place, since spammers that don't have a botnet could
|
|
|
|
|
buy tokens from harvesters. While the buying back would
|
|
|
|
|
temporarily let more spam through, it would only hasten the
|
|
|
|
|
self-defeating cycle leading to too many harvesters exploiting the
|
|
|
|
|
spammers.
|
|
|
|
|
|
|
|
|
|
Interestingly, one of the e-gold systems already has a form of
|
|
|
|
|
spam called "dusting". Spammers send a tiny amount of gold dust
|
|
|
|
|
in order to put a spam message in the transaction's comment field.
|
|
|
|
|
If the system let users configure the minimum payment they're
|
|
|
|
|
willing to receive, or at least the minimum that can have a
|
|
|
|
|
message with it, users could set how much they're willing to get
|
|
|
|
|
paid to receive spam.
