By the way, earlier in this thread I tried to ckarify the issue by giving a clearcut example as follows:
Suppose you have an established site about growing roses. Then you add a noindexed (but crawlable)page full of porn words and you also sell links to porn sites on it, and you also link to it internally. Do you really think that the Google algorithm will totally disregard that page simply because of the noindex tag?
I haven't seen any responses to this, so would like to ask again: Does anyone really believe that adding this page, even with a noindex tag, wouldn't hurt the rankings of the other pages on the site.
It's a bad analogy IMO and nothing like what this thread was talking about (adding a <meta name="robots" content="noindex"> element to a "normal" page... not one with tons of paid links to porn sites). Your analogy talks about a page that would ALREADY be violating Google's Webmaster Guidelines. Actually, if such a page existed and was indexed and Google penalized you for it, adding a <meta name="robots" content="nofollow, noindex"> to that page might even be enough to get the penalty lifted.
Regardless of whether a page with tons of paid, FOLLOWed porn links has a <meta name="robots" content="noindex"> element or not, having a page with FOLLOWed, paid links to bad neighborhoods is likely going to cause issues with rankings.
In your analogy, adding a <meta name="robots" content="noindex"> to cause Google to NOT index the content and URL does NOT get rid of the paid, FOLLOWed links which are a violation of Google's Webmaster Guidelines. Those links to the porn sites will remain in Google's link graph for your site, and can still cause you to be penalized.
However... If you have a site growing roses... and you add a brand new page with paid links like you're suggesting with paid links (even to porn sites) and have a <meta name="robots" content="noindex, NOFOLLOW"> element in the <head> of that page from the start of its existence, I doubt very seriously even such a page would negatively affect rankings of other pages on the site and/or Google's view of the site in general. The content of that page would be NOINDEXed so it would not affect your site. All of the paid, porn links on that page would now be NOFOLLOWed, so you would not be violating their guidelines.
Google has said repeatedly they have absolutely no problem with sites selling links... IF... they NOFOLLOW the paid links preventing them from flowing PageRank. And as long as the page had a <meta name="robots" content="nofollow"> or <meta name="robots" content="noindex, nofollow"> element, every link on that page (paid or unpaid) would be considered NOFOLLOW and therefore not cause issues.
