Let's just take Abby Martin as an example. The Wikipedia article that's up there now is the third one already, after two earlier pages on her were taken down by a Wikipedia committee of these so-called super editors "because she wasn't notable enough to warrant having a page of her own." This, notwithstanding the fact that the US mainstream media all knew who Abby Martin is because of her sharp criticism of those very same mainstream media in her own show on RT, Breaking The Set.
The fact simply was that the busybodies of the mainstream media and their shills couldn't stand that Abby Martin had a page on Wikipedia — a page which she herself had not created and had had nothing to do with — even though there are people with a page on Wikipedia who are far lesser known than Abby Martin.
Abby herself doesn't care about whether she has a page on Wikipedia or not, but she did comment on the fact that Wikipedia had removed the page, and she exposed them for what they are — including the fact that Wikipedia periodically keeps on asking for donations while they have over USD $1'000'000 worth in the bank.
