Welcome to WebmasterWorld Guest from 220.127.116.11
Through a side project of mine I have a contact at Yahoo! Engineering whom I contacted yesterday. He forwarded my e-mail to someone in search ops. That person requested I send him a list of user agents that aren't respecting robots.txt.
To me this is a unique opportunity to see if Yahoo! is serious about addressing this increasingly annoying issue. And thanks to Dan I have permission to deviate from our usual format to compile this list.
Thanks in advance for your help.
But hey, kick back and give things time. I know you're eager but they've got channels upon channels. (You were the first respondent in this, your own thread, because you didn't think we'd reply or that we weren't replying quickly enough. Heck, with mod-approval time and work skeds and such, I hadn't even seen your initial post until after you'd replied to it!)
Regardless of outcome, thank you for stepping up to the plate. Now get back to work:)
Bill, if you see this I've been trying to get in touch with you but your mailbox here always says it's full.
I can't figure out why we've been seeing this in our logs:

Also from 22.214.171.124 and 126.96.36.199

I thought it was a new set of exploits until I verified one of the IP as inktomi's:
IP address: 22.214.171.124
Reverse DNS: wj500040.inktomisearch.com
Reverse DNS authenticity: [Verified]
I can see doing one 404 test (well, not really, but I know some SEs do a one-file check). But 10? And from 10 IPs in under 10 minutes? Gimme a break. Besides, inktomi already asks for robots.txt about 50 times a day. So wow, why the sudden 404 assault?

No one else is seeing this?
...and the list goes on and and on. None of these files has ever existed on any of my websites.
...and the list goes on and on. They all belong to Inktomi.
I'll take a chance and forward this to Warren at Inktomi when I wake up.
Apparently the testing is not as "rare" as stated by that page -- unless yesterday was my lucky day. Shoot. Now I find out! :)
User-agent: Slurp China
However, it does seem to recognize that it should go away when it sees the code above, rather than accepting the
record and subsequently hitting my user-agent blocking code in .htaccess.
Now if I can just get "Yahoo! Slurp;" to quit listing my .css files in SERPs... Grumble, grumble... I've never seen this done by any other search engine before, but I had to add the Disallows for my .css files so that they wouldn't show up when search terms coincided with the terms I used in my .css file comments...

Why in the heck can't Yahoo just crawl pages from one place and let everyone share the pages?
I already block Yahoo China, don't make me block more...
I have posted a response from Yahoo! Search on a new thread started on this forum.
