So I am asking because my views are only challenged inside my own head, hence the need for external thoughts. But firstly the "governments will come and do bad things" argument - yes this is clearly and obviously a major problem - but not one solvable by technology in anyway. Fixing violent dictatorships is a IRL problem - one that requires enormous effort and sacrifices (see Ukraine for obvious example). We cannot p…

I am of the generation and mindset that online abuse is not real. Straight up. Log out, turn off the screen and watch Netflix, take a walk and calm down, block the offending user. It's not real. >I suspect we need better support for police in prosecuting such things We do see that! But mostly people on Facebook. Here we have had judgements of people who posted threats on Facebook because it is tied to your real name.…

This is almost certainly going to be decided by the "reasonable person" test - and if you were on the jury it's going to have to be a higher bar than I, but I suspect there will be some offences we will both agree on.

My main point is not that we need to lock up everyone who makes a threat, but that we as a society will have to adjust our standards to the new normal.

Once upon a time every conversation was fleeting, every discussion in a pub or bar was ephemeral. Even Einstein and Dirac would walk home chatting without fear of being overhead. Then someone imagined it would be wonderful for the whole word to hear the erudite wisdom of those two geniuses of our age - and Facebook and Twitter and social media made it possible for every conversation in every bar to be captured and recorded and published - and we found out that Dirac and Einstein were just sledging each other and most other conversations globally were worse.

The new normal is that, like speeding, most evenings, conversations in most bars actually broke quite a lot of laws, from hate speech to sexual threats and basic politeness. And now the police can hear them as can everyone else - and discretion does not work on this scale - we either enforce the laws or change them.

That's a conversation for each judiciary- and likely to be either a balkanisation of the social media world, or a race to the top (we can all have twitter as long as we all behave to the standards of the highest / politest society. I am not sure where I stand on that.

Is it serious - hell yes. We are looking at a global technology with global benefits for all humankind - and if we want to communicate globally we need to agree what the standards for behaviour are on this virtual stage - from contract law to human rights and freedom of speech. We are inevitably going to build closer contacts - Brexit is a salutary lesson - and how we deal with freedom of speech online is just part of the jigsaw - but a telling part.

I'm sophisticately sure they are not. They recommend a founder to ask users directly what they will pay for. Is that what PG would say?

Of course. Why wouldn’t he? That’s sound advice.

YC startup videos recommend not asking users directly what they will pay for.

Users freq. say they will pay for something but back down against other things.

How much should we fear de-anonymisation ? A lot of discussion on the thread are over "how can we prevent this". I would like to know why should we not embrace this and similar technologies? The benefits in my view are large - online behaviour tracks back to real life - and epidemiology speaking the value of millions of test subjects across every question are invaluable - from traditional medicine to "mass psychology…

What could possibly be the harm in allowing people to harass others based on posts they made decades ago? What could possibly be harmful in making a person who for whatever reason has changed their online identity easier to track? What could be remotely harmful about allowing Marlboro to find the accounts of ex-smokers? What could be the harm in tracking underaged users site by site? I'm sure this is completely harml…

I think this might be old age creeping up on me but I find it harder and harder to work backwards through "argument by sarcasm" to arrive at what you meant. I think clearly you are heartfelt in your views that having your identity online be a real one is bad - but I am not sure if that is because of posts you made years ago being linked back to you or nefarious advertising ?

The old posts issue is interesting- do you mean that there are posts from years ago you would find upsetting to be linked to you? Is this because you have chnaged your mind (a normal process society needs to understand) or because you said things thinking yiunweee anonymous that you would not have said under your real name? Far less of a social issue I think.

It does make for some interesting thoughts if we made everyone post under their real name.

I think people are sort of confused at what this tool is supposed to be which I will concede is partially my fault. The results of this tool are by themselves not indicative of having an alternative account. It generates the 20 most similar users for every single user on the site, regardless of whether they have an alt or not (there's obviously no way for me to know that for every single user). In your case further i…

It is a fun tool, I can assure you. It is just people have found use case you haven't foreseen yourself. I think your tool should have internal embeddings for each of the user. Also, most probably your tool uses cosine similarity for a search. Thus, I would like to suggest a feature: recognize simple arithmetic operations over user's embeddings, such as "thesz - 2 * patio11". It will make things even more fun, this w…

Really cool idea. I'd need to upgrade the VPS though so all the vectors would fit in memory but it probably wouldn't be too hard (right now I'm just storing a map of username string -> array of 20 username strings because my VPS only has 512mb RAM). I'll think about if I can do this in a way that is more resource conservative.

Wow. This gives a lot of false positives, but it found all ~10 of my old accounts over the years. The most interesting thing is that my writing style changed pretty drastically since a decade ago. Searching for my oldest account matches my earliest usernames, whereas searching this account matched the rest. The details of the algorithm are fascinating: https://stylometry.net/about Mostly because of how simple it is.…

Woof. I create new accounts on a semi-regular basis because I think cliques are the most corrosive factor to social media. Any time my account gathers enough upvotes enough I destroy it for another. I had four accounts. None are over 50% confidence, but when I look at any one account the others are consistently #2, #3, and #4. Now I’m thinking very carefully about what words I use to avoid linking this as the 5th acc…

This makes me melancholic. One should be able to express themselves without the overhead of privacy concerns.

It would be nice to make the names clickable. I don't think the list of pg alternate account is accurate. I checked a few. They have many oneliners that is typical of pg, but the topics and style don't look similar. I searched a few more and got better results. :) I searched myself (that I know that I have no alternate accounts). I recognize a few users that are interested in similar topics, and I discuss/upvote them…

But I didn't recognize most of the user of the list.

I think you are very likely to be wrong.

This is one reason why I like legal doctrines such as "beyond a reasonable doubt." Even a 0.9 match in a tool like this could be a coincidence, if there are millions of users. But that won't stop people from casually believing "aha it must be an alt account", based on some anecdata. It's so easy for something like this to be turned into a tool for a witch hunt, targeting innocents.

But a 0.8 or 0.9 match and something like Tor usage could be enough to justify a warrant. That's why I'm not sure I want to open source the code because I don't want to normalize this.
