Yes, many of the people who *use* it like it. It's the rest of the world
that hates it. See the top 10 reasons why challenge/response (C/R) is bad:
[1] You end up being a spammer (the majority of spam sent to you will
result in confirmation requests being sent to innocent victims)
[2] Spammers now send pretend confirmation requests, presumably to make
people less likely to respond to C/R requests
[3] Many people respond to C/R requests that they never initiated
(sometimes intentionally, sometimes not). Some people who are fed up with
bogus C/R requests respond to all of 'em, knowing that the spam will start
getting through to people hiding behind C/R.
[4] C/R companies have been known to send out spam and harvest addresses of
people sending to their customers, and apparently sell those addresses to
spammers
[5] The C/R system is patented, so most anti-spam programs using C/R have
legal liabilities waiting to be ironed out. The C/R program you buy today
may go under tomorrow.
[6] Confirmations sent to mailing lists won't work
[7] Confirmations sent to others using C/R won't work. If everybody had
C/R, nobody could send E-mail to anybody!
[8] People like me that offer a free service (in my case, helping people
with DNS) end up losing money (by spending time investigating and
responding to C/R systems, dealing with spam received as a result, etc.)
and sometimes get fed up with C/R systems and eventually stop offering free
advice (never knowing how many people won't get it), harming everybody.
[9] Legitimate E-mail from automated services won't be seen (such as when
ordering products online)
[10] Due to #1-#9, most C/R challenges are treated as spam -- if the
challenge never gets through, the response will never get through.
In other words, you're doing something nice for your customers, but at the
cost of annoying the rest of the world.
