This tactic has been discussed here for a number of months now. Nice to see that these sites are no longer appearing in the SERPS.
The sites that were doing this seem to have been completely booted from the index, too. Toolbar shows a gray PR.
I haven't checked them in a long time until now, but 2 sites that I know of that use this are PR0 and zero pages in the index. They are using trash domains with the mouseovers forwarding to the real domains. However, the real domains aren't apparently affected at all.
If this is algo-intentional, nice job Google! :)
LarryHat..
The trick was depoyed in the <body> tag...when you opened the page and as soon as you passed your mouse anywhere on the page you would be redirected to the target site..
so the 'mouseover' command was embedded such that the entire page was active when the mouse first hit the page...
The only way to see what was happening was to open the link in question from the SERPs and then use your keyboard to navigate to pull up the source code..and see the blatant 'mouseover' code with a destination url embedded in the <body> tag...
Good job Google...
I believe that one SEO had convinced clients either to put spammy Javascript mouseover redirects, doorway pages that link to other sites, or both on their clients' sites. That can lead to clients' sites being flagged as spam in addition to the doorway domains that the SEO set up.
Again, make sure you completely remove any doorway pages or links to spam that an SEO convinced you to put on your site before you write to Google about reinclusion. It reflects badly on your site if you write about reinclusion and then we check and the spam pages are still live on your site.
Seriously: If an SEO company is brave enough to point out the guidelines that Google suggests, then they are playing the game fair, as far as Google should be concerned.
Way to go Google for paying some attention to this trickery.
It would be nice that any page with an JavaScript mouseover redirect be removed from the index along with the sites they are represented with as there is no need to do that but to hide something.
That won't work, and from my tiny sample the domains being redirected to have retained their PR and general ranking, which is good because apparantly one cannot harm another's site with malicious domain level "onmouseover" redirects.
Additionally, even though my samples are doing it intentionally, as it would be obvious to any manual review, their real domains are innocent, have good content, and are as of yet apparently unaffected.
Fiction: A competitor can ruin a site's ranking somehow or have another site removed from Google's index.Fact: There is almost nothing a competitor can do to harm your ranking or have your site removed from our index. Your rank and your inclusion are dependent on factors under your control as a webmaster, including content choices and site design.
This contradicts what GoogleGuy is saying:

Probably a stupid question:-
I take it all us people who do Onmouseovers to change the text in the statusbar need not worry about this?
I think "right" means - need not worry! :)
