Politically charged issues such as global warming are prime targets for online sabotage
Acid rain is a popular term referring to the deposition of wet poo and cats.
No, not really. But that's what people looking at Wikipedia's article on acid rain could have read on December 1, 2011.
An anonymous editor had tinkered with the text. Over the next few minutes, the silly sentence winked in and out of the article as editors wrangled over the wording.
The incident is just one example of the "edit wars" that rage on Wikipedia, the user-edited online encyclopedia. Articles on politically charged scientific topics, such as global warming, evolution and acid rain, are prime targets for sabotage, ecologists report August 14 in PLOS ONE.
These articles are edited more often and more extensively than articles on less polarizing scientific topics, such as continental drift and general relativity, the researchers found after analyzing revision histories.
