What do posters want then ?
Maybe a button on the post dropdown that says " report and hide", so all posters can be user mods ? Or it could be restricted to the thread creator perhaps ?
That has problems too. Because then users can just hide any post for whatever reason. And what a mess that would be for the paid mods to sort out. Never mind if a troll gets bored and just hides everything.
I used to be a user mod on a forum. And it is not easy. I even had one poster who tracked me down and sent an email to my employer, complaining about the political views of their employees. When a post was reported, it was discussed among the user mods on a chat app. If one believes in freedom of speech, deleting what people say has ethical issues.
MN could just geoblock entire countries if they want. Or close it during UK night. Not good for posters such as me who are not in the UK.
I am on threads just now that have some posters that seem to report every post they disagree with. And that is where nobody is trolling. Yet these posters appear to go on prolonged debates with the mods over why posts should be removed.
And here is the thing. If one user has an idea for how to make the site work as they want, will that suit all users ? Nope.
As always with anything preventative, results can be difficult to measure. Because it might work 99% of the time and people don't see it working. But then that 1% does not work and people are up in arms about it, without knowing about the 99%.
I have not seen any of these troll posts by the way. And I am on MN a fair bit. And that leads me to ask, how many talking about these posts on these threads have seen them ?
