Months ago, I sneakily added subtle misinformation to a Wikipedia article (a pro wrestler bio) by making information up out of the blue (the "facts" I put into the article are not facts, but rather information which I invented) but because it does not look to be blatantly false, it was never removed. A few days ago, the information was quoted in a mainstream news article. I will not say here which article I "vandalized" or what newspaper's web site (and possibly print newspaper, as I'm unsure if the article on the web site was also printed in the newspaper itself) because then the information would be removed, and it is also possible that if I gave this information out, Wikipedia could do a checkuser on my IP or user name when I added this information and then find other IPs or user names I used to edit Wikipedia and block those as well. But what they can't do is take back the fact that a legitimate news source quoted Wikipedia "facts" as "fact" when in fact they were not facts at all.
That's a lot of "facts" in one sentence.
Anyway, I may be willing to give out a link to the article or select bits of the info via PM to people here who I trust but regardless, I wanted this to be known.
The date that the online article was printed is July 20, 2007.
