Wikipedia has started deleting hundreds of black hat articles. The site has also deleted 381 accounts who were engaged in undisclosed paid advocacy.
In addition to blocking the 381 “sockpuppet” accounts—a term that refers to multiple accounts used in misleading or deceptive ways—the editors deleted 210 articles created by these accounts. Most of these articles, which were related to businesses, business people, or artists, were generally promotional in nature, and often included biased or skewed information, unattributed material, and potential copyright violations. The edits made by the sockpuppets are similar enough that the community believes they were perpetrated by one coordinated group [Wikipedia blog]
Ofcourse, we don’t know what really happened under the hood – but you can take a look at the list of orangemoody articles here.
