No. The comments about “the monitors” do not refer to mumsnet HQ. They refer to the activists who monitor the discussions on here and then complain to mumsnet about them. Mumsnet used to accept complaints from individuals who are not signed up members of mumsnet. I don’t know if they still accept such complaints, but I assume they do. Those activists were trying to get FWR completely shut down at one point, spent years at it, targeting advertisers, that sort of thing. That’s who “the monitors” refers to.
