People keep bringing it up because two days later there still isn't an easily accessible statement on the subject from MN. People keep pointing to some comments buried in another thread with a completely unrelated title - which is absolutely useless to anyone who hasn't clicked on it or been pointed to it.
I'm a former community manager for a very large media firm - there's no detailed statement because MN are almost certainly in crisis management mode over this, as it's the kind of thing that will send advertisers running for the hills.
Still, a pinned, locked thread with a statement along the lines of...
"MumsNet is aware of an incident regarding illegal images being posted that occured on Sunday and are currently investigating the matter. In the meantime, images have been disabled and we will be removing all other threads on the topic to avoid speculation"
...should be the bare minimum almost two days on.
It's been dealt with and that's the end
No, it hasn't and no, it isn't.
This website exists based on the ad revenue generated by its users. There's no such thing as being 100% safe online, but users should have a reasonable expectation that there are adequate systems and protocols in place to mitigate.
I was stunned to find out that MN apparently doesn't employ 24 hours moderation coverage. It's inexcusable. User/volunteer moderators are extremely common, but there must be a specially trained resource available around the clock to deal with things like this.
Disabling images is fine, if that's going to be permanent. But that doesn't stop links being posted.
This issue won't be dealt with until MN puts things in place to prevent it happening again, and tells its users and advertisers what they are, so that an informed decision can be made about future usage.
