Like you upthread, I’ve reported factually incorrect posts of this type and had the “challenge on thread” answer. I have at times explicitly asked in a report for the thread context and all of a poster’s posts to be considered - that seems less effective these days, mostly only the one post which will often not be “enough” in isolation.
So perhaps if MN want us to do any fact checking put in place a proper process along the lines of community notes where we can flag up blatant falsehoods with usernames attached to the notes. Otherwise MN just becomes the place to go or a bunfight and whilst that may increase clicks in the short term it dies over the medium to long term.
This desire from MN to “counter on the thread” is at direct odds with their “do not engage with trolls/troll hunt” message.
I’ve said before I’d restrict the ability to change username, its far too easily abused. If people want to retain the ability to change then maybe one username in one topic or a request process to change name so that it requires a reason - just a step which takes longer than the automatic “switch to shitstirringname” whilst posting all sweetness and light elsewhere (which I’d classify as trolling).
I agree with this from @Saucery as well:
People should be allowed to express disquiet about what they observe to be happening in their communities. They should not be allowed to spout racist twaddle. That’s for MN moderation to act on and imo they need to be sharper and less complacent about it Achieving the first part requires the second.
@PhilippaGeorgiou There is no need to have wide-ranging boards - there are plenty of places elsewhere on the internet where people can whip up their own brand of frenzy
AIBU has a lot to answer for. Its killed a lot of the topics and combined with endless username changes just creates bunfight central. Just what every new or struggling mother needs.
