Someone with too much time and server space who decided to host a couple things because reasons.
I’m not sure there’s a purpose to it the way things are clustered here. Particular for anything of a political/news nature the very same post on one instance and com may get a completely different reaction on another. There are a fair number of people that I think of as ‘fire and forget posters’ in that they simply fire off posts but rarely interact with them after. Making this the default would likely encourage more of the same behavior, possibly leading to more spam.
Have you looked at your own? At this moment it shows me a total of 14 comments, 0 posts, and from a quick glance all but 3 of them are obsessing over this user who frankly is FAR from the worst of the users on Lemmy with regard to any kind of slant in their posts.
Take a moment to go wander through the landscape on the tankie triad and report back when you get a taste of what real propaganda spam posting is.
Or maybe something somewhere else, wouldn’t matter, if the user is canned from their home instance then they no longer exist to show up on your comm.
I’m not quite clear all the details but lemmy.ml is quite prone to banning people there for activities outside of their house.
If they where a .ml user and came onto your instance saying Russia/China/NK are bad that could get them the boot on .ml if they find out about it.
You would have to think of the user and the comm they post on separately. If a user is prone to spam/trolling then the home instance has every right to not host them, which would then have the knock on effect that they vanish from other places because that user no longer exists. It could be that the home instance got several reports saying the person was an issue.
I could see two significant problems here.
1: people getting lazy and just chucking everything into the generic bucket and the admins/global mods having a mess to deal with.
2: I’m the event of an ability to move content to another community other than the instance ‘global’ how do you deal with cross-instance moves? For example if the most prominent version of a comm is on one instance but a post gets put on another, the logical place would be to be on the more prominent community, but just dumping posts on another instance isn’t going to be well received I would guess.
The admin of a site, not only fedi ones but any site, can only control what’s in their reach. A user could ask as per the GDPR to have their profile and history removed, but data not in the control of the admin is not their responsibility.
Consider it from the perspective of a traditional site, if someone takes a screenshot of something you post and puts it up somewhere else the originating site has no means to control that or to remove the data from a third party location. The same issue has been fought since the dawn of the internet, people trying to erase past events that have spread far and wide. There are even proffesional services available to try and scrub such things, but in the end if all they can do is send takedown requests to another jurisdiction it’s going to be an impossible task.
More a speculative thought, but if those who do pay attention to negative feedback no longer see any, they may not take that into consideration when they put things up.
Say someone put up a post, saw no backlash on the front end, but then comes to look at the responses and sees a cesspit of hate. That’s hardly going to soften any mental harms it might otherwise impose.
Another thought here is messing about with such things, particularly in making them a default behavior, could disrupt comms where there is a strong voting aspect to it. The ‘am I the asshole’ type place that, despite the usual attempt to have them adjudicated by some nuanced comment system, inevitably end up using votes as a agree/disagree dynamic.
