I was thinking how one can deter spam, and
when you can't deter it, at least benifit
Here are my ideas:
a) First, Signup-Approval process.
I think this exists, but it's not clear how to use it.
I envision John Doe signing up, it going to the administrator's
in-box who then can approve or deny the signup.
b) Security Deposit
Perhaps it woundn't be such a bad idea to ask for
a credit card for a security deposit. Charge $5 or
so for "site access". This could help raise funds
to cover web site charges and other side charges
for many internet open-source projects. Kinda
like "dues" for being able to recieve posts
from the list.
I'm not sure about this one.. just a thought.
c) Two-Phase Post
When a poster goes to send it off to the server,
the server stores a local copy and then e-mails
back to the sender (after verifying that they
are signed up), an "approval" mail, much like
the confirmation to be added to the list.
The "approval" e-mail would have a copy of
the posting-policy. Reminding posters what
the requirements for the post should be: On-Topic,
Only 1 post per topic per 6 hour period, etc.
This would discourage mass posters from using
a list, and would also help those "multiple" post
people... who *really* should consolidate all
of their comments and post a single response.
If you combine (b) and (c) you could also
list a fine to be charged if the e-mail fails
to comply with the posting requirements.
A $500 fine for off-topic posts could be a
very nice way to raise revenue for an
Taking this further, you could have several
a) Questions ( free or charge to raise
revenue for bug-fixer awards)
b) Answers ( free! )
c) On-topic Commercial Announcements ($100)
d) Off-topic Commercial Announcements ($500)
In otherwords, don't "fight" SPAM, merely turn
it into a source of revenue for open-source projects.
People won't mind receiving SPAM if they *know*
it cost $money$ to the poster and will be used
to cover web site costs, "awards" for active
programmers and bug-fixers, subsidized
manual printing, etc. (There are thousands
of ways to spend the money in a fair way)
