The first and most important step to participating in the "We the People" is finding petitions that matter to us. But the White House has blocked all search engines from crawling the petition archive.
Specifically, the White House is using the standard robots.txt file to prevent search engines from crawling the "We the People" petition repository.

Remove those directives, allowing Google, Bing, Yahoo and other search engines to crawl this repository.
