Introducing a refunding system adds a lot of complexity for not much

Think through the mechanics of this whitelisting system, i.e., the
bookkeeping and msgs back and forth.

(eliding some stuff we mostly agree on)

What about the "attention" costs, when nobody for example looks at an
Amazon mail or even a useful msg from their bank because they're too
busy deleting everything that isn't absolute top-priority (like from a
relative or lover.) They're just swamped.

Anyhow, I guess either spam is a big problem or it isn't.

Everything I say is based on the premise that spam is a big problem.

If it isn't then we are truly wasting our time here.

Well, if you don't see spam as much of a problem then surely most
anti-spam proposals are going to seem too costly, right?

Maybe I haven't had enough coffee yet but I truly don't understand
what you're asking here.

You must live in some low-density population area, here in Boston the
letter carriers won't take outgoing mail. I tried one day and the guy
just sneered "put it in a box, that's all I'd do with it!"

Obviously there are people emptying those mailboxes but it's...where
are we going with this?

Ok, nothing stops you in this scheme from returning an email to the
sender. Maybe it could even be made free, probably just like any
Mailer-Daemon bounce.

What I don't think is a good idea is the sender getting their postage
back. That's a lot of bookkeeping and I don't see any reason to

I believe the USPS now throws those away. The return postage only
covers a first-class letter or whatever.

If it's first-class mail, that's one reason first-class costs more.

Big exception since that's almost all of what bulk paper mailers use!

I think it's very important to eliminate any definition of spam from
the system. That's just a rat hole.

You stop spam by making it too expensive for spammers to operate in
any effective manner.

True story:

I remember when I was about 16 years old I went into this place in
Greenwich Village, still there I believe, "The Cafe Wha?". They didn't
serve alcohol so it was someplace a 16 year old could get out of the
rain and hear some live music.

At the door was a guy with a coffee can, "Cover Charge: 25c"

Even way back then 25c wasn't much money, about the price of a couple
of packs of gum.

I asked the guy: Why a 25c cover charge?

He said: It keeps out the riff-raff.

It keeps out the RIFF-RAFF???? 25 CENTS?

He yelled back: YOU'D BE SURPRISED!

Well, surely he knew his business.

We're trying to keep out the riff-raff while not overburdening the

Maybe I should dub this the "Cafe Wha? Proposal" in their honor.

Permission to speak frankly:

You want a moral component, you want this to identify the good from
the bad. You keep coming back to that.


I just want the spam to stop.

And I think when you make that leap and let go of the moral or
judgemental aspect solutions start to appear.

I don't want to make better people out of spammers.

I don't want to put them behind bars.

I don't want to punish them.

I don't want to reward the righteous (except by default, less spam!)

I just want to put spammers out of business!

I want to change the ecology so it makes it impossible for them to
operate in any effective manner.

I keep saying "effective" because sure you might get the occasional
spam anyhow, particularly in the beginning as they try to save their
business model, but I want to run them out of town.

Whitelist shmitelist.

You're turning this into a two-way system with active feedback which
is EXACTLY what I say is to be avoided.

 > You could decide for yourself which messages from the airline you don’t consider SPAM, with the added benefit that you get a small amount of money for each message you don’t actively claim isn’t SPAM.

Easier to just toss the ones you don't want.

Think this thru, you really want to look at each msg and decide if
it's spam or not and if so perform some function...?

Sure, some people do that sometimes, report spam, but really life is
too short.

I say put the spammers out of business.

Active feedback, bookkeeping, unnecessary.

Ya know, I can't go thru these supposed fundamental flaws one by one,
show they arise from misunderstandings etc, and then come back to "I
believe your approach to be fundamentally flawed".

Doesn't leave me much to respond to.

 > Ah, but BofA didn’t hire them to break the law. BofA hired them to send the SPAM to the list they promised BofA was entirely opt-in users who chose to receive their mails. The fact that they lied to BofA means BofA doesn’t have any liability. The fact that BofA profits from this lie without consequences means that BofA has no incentive to go after them for a refund or avoid using their services in the future.

Actually, that's not true, speak to someone who understands agency law.

BoA might be able to in turn sue them for breaching a contract but BoA
can still be held liable. Those aren't mutually exclusive.

Really, that's agency law 101.

I realize people think about it for a minute and say "that's
ridiculous!"  but that's exactly how it works. And why business
liability insurance covers events like that, or should.

Intent is not a factor which tends to be the source of a lot of "folk"
law beliefs like this.

Review agency law.

BoA can be held liable. BoA can in turn sue the spammer, if they like,
to recover.

That avoids precisely what you're suggesting, transferring liability
to a judgement-proof entity.

Yes that can still be done in many cases but not as you describe.

But why are we here exactly?

Chapter 13 is personal bankruptcy.

Oh c'mon, then so is every other situation where you have to pay for
something, including credentials.

Are SSL certs a protection racket/extortion scheme?

I'm serious!

I wouldn't consider investing a dime without talking to some spammers
or ex-spammers of note.

There're a few of them who'd probably be glad to talk for some prison
canteen credits.
