I had reason the other day to ask Yahoo a question about it’s directory and someone who was acting as an agent for the directory. I used their “other abuse” option on the contact forms to ask if the reseller was legitimate.
After a couple of days I got a reply focussed on spam. I replied hoping that I might trigger a human to actually read what I had posted. Given the delay in sending and receiving then surely there was a human involved? Computers are much quicker than that!
