an evil jump to the Google’s first page
For my goals, the query "phpbb spam" should return Textual Confirmation and Links Rejector tools on the first page. No luck so far, but I managed a nice trick to get there indirectly:
Some time ago, Lauri Harpf (A Promotion Guide) published a nice article "How to stop spam on your phpBB forum", in which he pitched the tools.
I announced the article in the bbAntiSpam forum and the blog "Spam Bots and CAPTCHAs".
In a week, the article appeared on the Google's first page.
