If it's redundant, why not report it to be deleted?
Yeah, I'm with you. But, people are
lazy and being able to just quickly click one button (instead of having to click once, lose focus, enter some text, and then click again) will appeal to many more people, I think. Also, having precisely defined rules (e.g. if 9 of your peers agree(d) with you, then the post will be effectively "nuked" without further ceremony) is more satisfying (to me anyway) than being at the mercy of a hit-and-miss moderation policy.
If it takes 10 or more "hits" to hide a post, I'm not going to waste my time tagging them.
I had the same thought. I think it might work best if the post
immediately (or maybe with a second, user-specified threshold) disappears from your
own view, but only disappears from everyone else's when the global threshold has been reached. I could see myself clicking that button
all the time.
It would be much better if it's linked to the Trust list, so based on the user's who's judgement you trust already.
Yep, or something similar, like a new "post curator" list.
Other systems that the forum already has, such as trust, sometimes suffer abuse, let alone this one.
That's true, but I'm not saying that this system
won't be abused, I'm saying that it's possible to select the parameters in a way that would make that abuse impractical to execute. (Of course, there's a balancing act here: if you set the countermeasures
too aggressively, then the feature won't work that well in practice, because too many people would have to click the button for the "threshold" to be crossed.)
Then, the fact that the post is hidden in the topic, it will not disappear from the list of posts made by the user, which is probably the list that campaign managers analyze.
When I said the post would be "hidden from view", I meant the user's post history, too. Although, I'm guessing some campaign managers might use tools that rely on post archives (like ninjastic.space), and that needs a slightly more complicated solution (maybe a new endpoint to get a list of "redundant" post IDs for a given user and time frame).
