Need help Finding Thread / Article

Thread contains a link to an article about spam detection

[Hemsell]

I once followed a link out of this Forum to a PDF file written by a guy with an indian sounding name. He now works at Google. In the article he discusses how to detect spam in Google. He covers cross linking between sites that share the first three octets of a class c address.
I found a thread referincing the article, but not the link to the article.

Could someone help me find it please?

I searched Google and this forum for over an hour now.

Is it in here?

Hemsell was it subject matter related to the article by Krishna Bahrat mentioned in this thread?

[webmasterworld.com...]

Also, there was a bit of a discussion about C Class Penalties [webmasterworld.com] back in December.

Is that it?

[Hemsell]

Yes!

Thank you both for answering.

Heini, Thanks for the link to that post, alot of good info there but the link Marcia posted was it.

I saw GoogleGuys suggestion to cut this forum up a bit, I would have to aggree just because finding things in the past postings is so unweildy.
Sifting through 50,000 posts is a nightmare when you are looking for one tiny nugget of valuable info.
It also leads to new and pointless posts like mine here that serve no porpose than to find other posts!

Thanks again,

Todd

Hemsell, first thing I did was looking into the library, linked from the froum index pages. Often this brings up stuff fast.

Todd, please go ahead and post that in that thread, then.
