I am having a discussion with 
I see no reason why users shouldn't be responsible for their own actions
And I replied:
OK we can agree to disagree about one-time mistakes being punished eternally. Seems harsh but sounds like that is a firm line for you.
The Horror of Eternal Punishment
What I am warning about is people making a single mistake, or being a victim of something horrible, and following them for eternity.
Already it is possible to find photographs of unwilling nudes that were shared. Remember when 4C and Reddit shared celebrity videos and stills stolen from celebrities' hacked phones?
Plus all those blackmail and revenge websites that sprung up to shame partners and exact revenge after breakups?
With centralization at least you can get the websites to take down something given laws in your countries, and money for lawyers.
You can't eliminate it entirely due to caching, archiving, and copies still being out there. That said, the centralization makes it harder to discover.
On a forever-blockchain, though, even if the interfaces and apps agree (which, "muh freedumb" folks object to), the blockchain itself, and the APIs that access it, don't have to do crap.
It's immutable and permanent.
My guess is
He makes the point though it is their fault. Given how many kids this involves, I don't think that is a good-faith argument, but what if it is someone you care for?
What if it was not anything YOU did?
What about
- victims of rape,
- pedophilia,
- sex trafficking,
- sex slavery ...
It's difficult enough for the victims of these things without the added horror of expecting the sharing of it to go on forever.
People were grooming kids online right back when ICQ was a thing and webcams were new.
What about the people who are filmed in hotels/motels, AirBnB, gyms?
People go for years without even knowing it happened to them, until one day they get a message blackmailing them.
What about plain identity theft and doxxing?
Most of us have heard of swatting and doxxing happening even in supposedly safe environments like online gaming and Club Penguin.
Swatting can't happen without someone getting info about the intended victim, so the two go hand in hand. Most of the time the doxxing happens first, enabling the swatter.
Online games and forums are pretty good at getting rid of info eventually, there is no way to do that on a forever blockchain.
@jerrythefarmer is the one perfect individual ever?
Human stupidity and ignorance will remain abundant for as long as we deprive these people of any responsibility.
You have never made a mistake Jerry? Ever?
All the times you connected an app, you did a lot of technical auditing first? I would love to see your perfect process.
What about when the app changes hands? Perhaps they were hacked, or maybe they sold the company. What then?
Plus the people that you care about, they never ever make mistakes online?
Personal Stories Time
A couple of stories to drive home my point.
Creepy Flickr Dudes
When I first got into Flickr around 2005/2006 I would post perfectly normal pictures of my family, and this included pictures of the women and kids in my family. Normal, fully clothed, life stuff, and yet creepy dudes would come out of the woodwork and post horrible messages.
That taught me to never share anything like that without private settings, but even private settings don't guarantee anything.
Angry Get Rich Quick Victim
Years ago, my co-author and I wrote a book that went on to some reasonable success. Within the pages we talked about how people can make money from producing content and gathering a community, with the caveat that it is long, hard work. The publisher gave us a slightly hyped book title but we thought it would be ok because of the sober message inside.
Fast forward to a mentally unwell person threatening my friends family at his home, because he found which district my friend lived in and trawled the neighborhood until he found him.
Brother Locked Up?
My two aunts from different sides of my family got a very convincing phone call supposedly from my brother saying he was locked up in Mexico on drugs charges and needed bail money but he specifically requested nobody tell my parents.
Fortunately, they checked with me, otherwise, they would have wired money to scammers because they care and the seeming risk was lower than the risk of leaving him in a bad situation.
Take a guess how the scammers managed to get all that personal information. Enough to convince a couple of older, but smart ladies.
People are fallible
Anyone who believes humans can be error-free has not many many! 馃槅
In fact, the weak link of most security is the human operator.
One of my first entry points to the internet was bulletin boards in the end of the 1980s. Even back then you would hear as many stories of people over-sharing and getting into trouble as there were of people meeting and getting married in these venues.
When we started opening up to the internet via Usenet and other systems, that flood of college students showed how unguarded and overly comfortable people can be. We saw drug deals right out in the open, people gossiping to spread lies to hurt each other, test scores (and answers!) in plain text. Even a photograph of a key being used to create a good enough replica that it opened the door, this was before digital cameras were in everybody's pocket.
