Google's Webspam Team using Sitemaps to Alert Webmasters of Penalties

SEO Help Direct from the Google Webspam Team

Matt Cutts says if you get a message in your sitemaps account similar to the following, you're a part of an experiment by the Google Webspam team to alert legitimate websites to problems with sites (re: Google's quality guidelines).

No pages from your site are currently included in Google’s index due to violations of the webmaster guidelines. Please review our webmaster guidelines and modify your site so that it meets those guidelines. Once your site meets our guidelines, you can request reinclusion and we’ll evaluate your site. [?]
Submit a reinclusion request

Not receiving an error message doesn't necessarily mean you are safe. Google does not want to help tip off spammers. They'd prefer to let them quietly waste their time working on new doorway and cloaked pages - as their indexed pages either disappear without a trace or get overlooked by the bots.

Notes on vBSEO

• Since most forums will be considered legitimated sites (i.e. content is generated from members, not spam or automation), this feedback could be very useful. Being alerted to some small problem on a forum, would be very beneficial to admins.
• vBSEO will always remain 100% whitehat.

For Discussion

• Is Google getting better at flagging and blacklisting doorway and cloaked pages?

I was warned about hidden text...now does this warning mean clean it up or does it mean ...warning clean it up banned for a month?

I've cleaned my hidden text that I really was not aware of and I jsut want a second chance without being removed..Is teher any way to contact Google webspam team...and plead my case...

I am not sure that Google still can determine cloaked sites pretty good. I reported couple sites that used cloaking and blackhat seo tactics 2-3 month ago and their content is still indexed. Lets see if it will change from today.

this article is a year and a half old....

So after 1.5 year there is still no change

I totally missed the date
