I don't know, but I knew they were really screwed up back when Laura Bates was writing her column about everyday sexism. A lot of the time the comments were very critical, because the columns were so, so bad. Making assertions about certain behaviors increasing because people who followed her on Twitter said so, or assuming certain behaviours which sometimes seemed like bizarre aberrations (someone throwing a sandwich comes to mind) were motivated by sexism.
Anyway, that is by the by, but people would often pint out that her the basic facts underpinning her column weren't particularly well supported.
The Guardian moderated these comments out in short order. And then, they asked readers in a special column what to do about all the criticism under their feminism articles (Jessica Valenti was the other writer who came in for a lot of similar critical comments.)
The readers responded with - please have the editors hold this stuff to a higher standard.
The Guardian response - disable comments under the articles.
So something had gone very wrong way back then, before gender issues were in the news much at all.
