Thank you. I am now in contact with them. I must admit it is the first
time I ever got any kind of abuse response from Yahoo!, but the people
who contacted me seem serious. I will know more later on as to how well
they handle it, but they seem like people who want to help.
All Inktomi/Yahoo crawling is done from 188.8.131.52/22; the whois
entry for that block says to report issues to email@example.com
Have you tried alerting them to the problems yet?
If yes, and if you didn't receive a response, please forward me the mail
that you sent, and I'll see to it that the right people see it.
