I came across this website in my backlinks: http://www.newdomain5.info/ Take a look at the beehive of a spammer. He was even too lazy to hide the site index or the php files. How can this site be reported to the search engines? They usually don't take spam reports unless they were found in serps, but this is obviously a site they would like to keep out.
Inside those folders you can click on Adsense "Ads by Gooooogle" link (not the ads) and report to Google the violations of the page.
Damn, now that's lazy. I would go the route of reporting the Adsense violation for sure, at least take away his ability to make any pennies.
Yeah you can penalize his/her Adsense account. But also based on experience reporting the URL to the link provided by Chios also works quite quickly. I had one site banned a week after I made a report.
What is clickbombing and what's not nice about it? When I reported it to Google they gave me an email address I can use for future complaints : .
