A few gigs of zeroes will prevent random drive-bys. At that point the partition and filesystem table of at least the first partition is overwritten and you "can" recover files off it but you'll be missing filenames and at least half the files will be corrupt due to fragmentation losing track of which files are where.
I agree with Ono that shred is a good tool for this. If you don't want to use that, try increasing the block size to at least 1M if not 16M to reduce the overhead.
Seems asinine to me, we know that cops in schools (and even cops called in to respond to a shooting at a school) will literally stand around while kids die. Of course the real answer is to have a healthy society where schools aren't prisons-slash-daycares...
A cop doesn't prevent a student from getting stabbed, they just barge in once it's over and act like they're doing something useful.
The whole country needs it IMO, unfortunately only publicly-owned land with that as a designated use is the equivalent; there is no non-owned land in America, only public, private, or private-but-abandoned-and-about-to-be-repossessed. I agree that private property as "this is all mine even if it looks like an empty plain and if you so much as hover above this imaginary line you're a criminal" is an awful way to run a society
It's unfortunate but there are a ton of shitbag people out there whose method of using the Internet is to be as shitty as they can be. Whether it's fascism, abuse, sexism, racism, harassment, or just being the kind of person nobody wants to be around, these are real-life humans who've always been around and volunteer moderators/admins have always had to deal with. It's as old as Usenet and if you've ever done in-person community management you know that it's just a feature of our society in general. (People are just a little more wary of being yelled at and punched in person though.)
My workaround for now is to try viewing a post on that community; the Subscribe button on the post itself seems to work a little more reliably.
The issue may already be fixed in code however:
There are definitely people out there who espouse the same beliefs as the Nazi Party and use the same strategies to weasel their way into popular discourse. Even as far back and as mildly as the US election with Obama, I was struck walking through the German History Museum in Berlin by how similar Nazi propaganda posters were to the kinds of rhetoric seen on Fox News and spoken by Republican politicians. Calling everything they don't like Socialism, or Globalism, for example, when the targets are hardly aligned with those ideologies, is literally copy and paste what the Nazi Party did. Not just "everything I don't like is Nazism," but like the specific phrasing and strategies they use against specific targets like Black, Jewish, LGBT+ people, and foreigners are nearly identical. When the mainstream dismisses it as "economic anxiety" or "ignorance" or "right wing populism" we're failing an open book test, because it's all been written down for 80 years and you can tell that these neo-Nazis have read it.
This is a period of explosive growth and adjustment for Lemmy, it'll take awhile for things to settle down and for us to see what people's true colors are. Hopefully anywhere that actually harbors hateful or troll content will be marginalized and the mainstream instances will be properly moderated, but it'll be a continual battle since such people always want to find new ways to spread awfulness. If we're lucky, instances that have good track records will federate with each other. If not, people can vote with their feet.
They tried to overthrow the federal government last election and are responsible for countless hate crimes and fomenting prejudice and violence against marginalized people, including supporting new fascist laws in the past few years. They are dangerous, their ideology is dangerous, and their speech is used as a weapon to harm people. I'm not running away, I'm saying any "stadium" owner can and should be expected to ban such assholes from the premises. As the saying goes, if a bar owner lets Nazis congregate in the corner of their bar, it's a Nazi bar. "Not all Germans" physically committed a genocide, but all of them tolerated or endorsed Nazism to the point of allowing it to happen. When good people see evil rising, they get involved and disrupt it, they don't stay quiet and let it grow.
Which is why the very first question an instance admin or moderator needs to think about and answer for all to hear is "how will you handle Nazis?"
More like why aren't more people holding Facebook accountable for the genocide they aided and abetted. They're murderously incompetent at best, and global enablers of fascism at worst. https://www.theguardian.com/technology/2021/dec/06/rohingya-sue-facebook-myanmar-genocide-us-uk-legal-action-social-media-violence
Excellent example of why giant instances are bad ideas. Nazis love forcing you into a "throw the baby out with the bathwater" type choice because it means they can continue their hateful, destructive, genocidal behaviors without consequences. They're usually not stupid, they know what they're doing is wrong, they just want to keep getting away with it. So they'll go nuclear on anyone and everyone in order to maintain their comfy corner of hate.
Any moderator (or stadium owner) who doesn't give Nazis jerking off in a corner a lifetime ban is negligent, as you said.
