Thanks for the lecture.
Every item is stored with an intent somewhere between storing the
saver's attention and attracting attention from other people. Normal
users lean to the left on that axis, and spammers to the right.
Unfortunately, the actual mechanism for both are largely
indistinguishable and it is the intent that matters.
Like I said, this is more than a minor annoyance for me and the team.

I already explained, but you didn't understand. CAPTCHAs prevent
atomated
spambots to post comments (on some blogs), register for services
and similar
things. There are many clever ways spammers figured out to get
their bots
around CAPTCHAs, but even if they do they are considerably
slowed down -
they planned to hit these HTML forms hundreds or even thousands
of times.
On del.icio.us import, to posion tag listings with thousands of
spam sites
you need only one "hit" (file upload, to be exact) and that's
why their bots
don't even matter - spammers can easily take several minutes of
their time
and upload the file by hand, circumventing any robot-blocking
methods
del.icio.us team have put up.
The trouble here is defining spam on social bookmarking sites.
Spam is
easily recognized on blog comments, wikis, but on social
bookmarking sites
like Del the whole point is to submit links to other sites! That
means
everyone who's using Del is a kind of a spammer - our links
appear on our
pages, in tag listings, in other people's feeds... Sometimes I
stumble upon
a bunch of cool JavaScript resources at once and I tag them all
at once,
resulting in even 10-20 new links in a short amount of time. To
some people
who are not interested in JavaScript that is spam, but to most
of the people
on Del it isn't, since it is one of the most popular topics.
Some of my
friends already complained about me spamming them with Ruby on
Rails links
:)
So new Del users want to share hundreds, sometimes thousands of
their "cool"
links at once by importing from their browsers, other social
services...
That's OK, we want to allow that, do we? But spammers want to do
exactly
that, too - they only want to "share" their "cool" sites about
poker,
viagra, mortgage loans (and similar) with us. They want to do it
because
people then go to those sites and actually buy viagra, play
poker and
takeloans. And not only spammers make money by "sharing" links -
many
people get
money too as ad revenue by submitting links to their own sites
and articles
they wrote. We can't blame them for that.
If we can first define spam on social bookmarking sites, only
then we can
start talking about slowing it down or even blocking it.
Joshua, did/does del.icio.us have problems with automated
postings or
spamming by hand? Did the team take some measures to detect
those? Are users
blocked when they make too much simultaneous posts? We'd like to
hear your
experiences.
