Yeah. Also, if a specific source is used a lot, it often gets put on a discussion where people vote on how reliable it is. If it's considered unreliable, the use of it will be banned.
Love the use of the "we" word here. :) What is counted as a reliable source is voted on on one of Wikipedia's meta pages. So "reliability" is not based on any factual circumstances, but on whether the vote is won or lost. And you can trivially game that using sock/meat puppetry. Notwithstanding, White's claimed policy heavily favors Western media giants such as The New York Times and The Washington Post which many editors know about. However, the actual information they publish are often much less accurate than what is published in specialized trade magazines or even activist blogs.
They sure do, it's still those who amass the most votes who gets to decide. And it leads to clownish ridiculous results. ADL is listed three times as green, yellow, and red. Comment says "There is consensus that the ADL is a generally unreliable source for the Israeli–Palestinian conflict, due to significant evidence that the ADL acts as a pro-Israeli advocacy group and has repeatedly published false and misleading statements as fact, un-retracted, regarding the Israeli–Palestinian conflict." So an organization that has "repeatedly" been caught spreading false and misleading statements is still a reliable source. LOL
