This highlights one of the problems with Wikipedia. I find it just as frustrating that somebody has been able to do this without any controls in place to maintain the integrity of the page.
I understand that Wikipedia operates on a mentality of "everybody might have relevant information to add" but this sort of behavior remains an issue.
To be fair, Wikipedia does have editors and moderators to combat this sort of thing. And the comments were removed in a matter of hours I believe. It's not perfect system, but they do have employees in place for this sort of thing.
Evidently so - I initially went to the posted link, not to Wikipedia. But evidently it failed long enough for somebody to achieve a screen cap of the offensive page and for NPR to feel it merited a story.
To me, it simply highlights why I rarely consider Wikipedia when I want information, while a friend of mine considers it a valuable resource within its limitations.*
*If you want a clearinghouse location for what is essentially niche content (e.g., order in which Disney films were released by year, minutiae re Star Wars/Star Trek/Dune/Firefly, (other various topic of interest)), most of which, admittedly, most people won't actually mess with, Wikipedia can be useful.
