I shall pin this comment to the top of my curriculum vitae.
"You see, dear grandchildren, your grandfather used to have an apple orchard. The fruits were so sweet and nutritious that every town citizen wanted a taste because they thought it was the only possible orchard in the world. Therefore the citizens gave a lot of money to your grandfather because the citizens thought the orchard would give them more apples in return, more than the worth of the money they gave. Little did they know the world was vastly larger than our ever more arid US wasteland. Suddenly an oriental orchard was discovered which was surprisingly cheaper to plant, maintain, and produced more apples. This meant a significant potential loss of money for the inhabitants of the town called Idiocracy. Therefore, many people asked their money back by selling their imaginary not-yet-grown apples to people who think the orchard will still be worth more in the future.
This is called investing, or to those who are honest with themselves: participating in a multi-level marketing pyramid scheme. You see, children, it can make a lot of money, but it destroys the soul and our habitat at the same time, which goes unnoticed by all these people with advanced degrees. So think again when you hear someone speak with fancy words and untamed confidence. Many a times their reasoning falls below the threshold of dog poop. But that's a story for another time. Sweet dreams."
“Engineers have invented a new way to remove health-harming ‘forever chemicals’ from water – using 3D printing.
Researchers at the University of Bath say their method, using ceramic-infused lattices (or ‘monoliths’), removes at least 75% of perfluorooctanoic acid (PFOA), one of the most common perfluoroalkyl and polyfluoroalkyl substance (PFAS), from water, and could become an important tool in future efforts to eliminate the chemicals from water supplies.
Their findings were published this week in The Chemical Engineering Journal.”
[…]
“Testing of the monoliths has surprisingly shown they have become more effective under repeated use – they undergo high-temperature thermal ‘regeneration’ treatment after each use. This is something the researchers are keen to understand more fully with further experimentation.”
If a website could be sure none of their users are malicious/bots and all of the users are perfectly rational and virtuous then public or private voting wouldn't matter either way. That being nearly impossible, why not a reputation based system like Stack Exchange? Only when an account meets certain requirements they can vote.
To boot, on the website tweakers.net one can actually vote -1, …, +3.
- +3: “Spotlight comments are of such high quality and substantive value that they clearly stand out above the rest”
- +2: “Informative and interesting comments that are a useful addition to the discussion in an on-topic thread or the information in the article”
- +1: “Nice on-topic responses with knowledge that is common knowledge”
- +0: “Comments that do not contain a relevant contribution, but are posted with good intentions”
- -1: “Flamebaits, trolls, misplaced jokes, unnecessarily hurtful comments and other comments that violate our terms and conditions or house rules”
A hammer is a tool because no one but the hammer merchants gain financially if everyone were to buy a hammer. Crypto“currencies” are not purely tools but instead multi-level marketing pyramid Ponzi schemes because as soon as one has it they have everything to gain the more people buy it after them.
“Thirdly, early adopters mine or buy large proportions of the total supply at negligible costs while late adopters mine or buy negligible proportions at large costs. It follows that holders immediately have every incentive to get as many people to buy after them. Like stocks? Like stocks, but without the dividends or anything tangible in the real world [10]. Congratulations, you got yourself a pyramid scheme †.”
“† The stock market has largely become a pyramid/Ponzi scheme as well since most of the money does not exist and profits come from buyers or new entrants, i.e., the greater fool [16].” —Money corrupts; bitcoin corrupts absolutely, https://www.cynicusrex.com/file/cryptocultscience.html
It gives credence to greed incentivizing unethical contraptions.
Immoral baskets that incentivize greed are to be avoided.
Then they should transition away from multi-level marketing pyramid Ponzi schemes too. I deleted my Protonmail account when Proton began peddling crypto“currencies”.
What does the acronym SO stand for?
Fair enough. But a workaround that I have implemented before my previous “Reddit nuke” was saving all my most valuable answers and hosting them on my own website. What I would do now is just replacing all my comments with a link to my website: POSSE, Publish (on your) Own Site, Syndicate Elsewhere. Well, almost POSSE, because I'd be removing the actual content from Reddit.
Lies, as in that it's not really “blocking” but a mere unenforceable request? If you meant something else could you please point it out?
Should one remove all Reddit posts and comments?
Do the advantages of deleting one's entire Reddit history outweigh the disadvantages?
I have previously nuked my first Reddit account because it felt satisfactory to be completely detached from a platform one considers unethical/bad. Though, I have garnered quite some history on a second account—because Duty Calls*, of course—and I'm considering doing the same.
However, I don't want to do it impulsively. I think I might be blind to some disadvantages. What do you think?

Unfortunate indeed.

Had it happen to me too. They'll refund you for this. Just be polite when asking for it.
My review on the Play Store: “Premium is a scam. Hides likes which come from all over the world (clickfarms?) even though I set my radius to 5 km. But of course they only show you the fake likes (all of them) after one pays for premium.”
Thanks for the share, had no idea. It felt so nice that I already added two contributions to OpenStreetMap.
“What's a browser?” —the general populace
I just install uBlock Origin on every device I come across. Graffiti software.
I can't disagree with what you quoted, nor state that it is a good argument—it isn't, as was already pointed out and which I do agree with. I'm emphasising that they are not saying “the bombings were not as bad as people think”.
I'm just addressing the fuss that's being created. They are clearly not saying “the bombings were not as bad as people think”, but the headlines and articles make it seem so.
By doing this we are using the same spurious tactics as they are. Inundating people with blown out of proportion news like this will desensitise them to step into action when it will actually be warranted—the boy who cried wolf.
They spew tons of misinformation/disinformation/fallacies that should be addressed instead.
Fever Feels Horrible, but is Actually Awesome! - Kurzgesagt
“Fever feels bad. So we take medication to suppress it – but is this a good idea? It turns out fever is one of the oldest defenses against disease. What exactly is a fever, and how does it make your immune defense stronger? Should you take a pill to combat it?”

Fair point. I should've made the distinction. But in any case, nuclear power plants aren't bad.
- Our Friend The Atom (1957), educational video by Disney.
- The Safest Source of Energy Will Surprise You, spoiler: nuclear energy is the safest.
- Titans of Nuclear, nuclear energy podcast. If you watched the series Chernobyl, I highly recommend this podcast's five dedicated episodes expanding on the misinformation it contains.
- Nuclear Energy, Zondag met Lubach.
- We have a solution for final disposal of spent nuclear fuel.
Not defending these two unethical bullies in general, but on this particular paragraph they are totally taken out of context. It is obvious that they are not downplaying the atrocities of Hiroshima and Nagasaki but merely stating that nuclear energy is not bad since people are already living there again.
On desktop, either use:
- LibreWolf (FireFox); uBlock Origin is installed by default.
- Vivaldi browser (Chromium); has a native ad blocker but obviously supports extensions, and will try supporting manifest V2 as long as possible—“as long as Chromium core supports Extension Manifest v2”. Also, why the “not completely open source” criticism is unwarranted.
