Userscript to Display Age/Karma of HN Users
Small script to display account age/karma next to all usernames, so you have that info available to you without clicking through to someone's profile. Opus 4.6 written, it's a mess but it works :) Using with Tampermonkey on Firefox.

- MHMarkdown HN profiles at {user}.at.hn2024 · at.hn · ▲459
Very opportunistic toy project as I saw the domain was up for grabs: 'at.hn' is a little site where people can have their own subdomains for whatever their HN username is (opt-in only by adding a slug to your bio). It doesn't really do much. Just shows your HN bio rendered as markdown plus meta stuff. I'm thinking of adding an aggregated user listing on the homepage so people can explore profiles. There's a bunch of interesting people on HN but discoverability is a bit longwinded. I'm wondering what other features people want. Otherwise shall likely leave it as-is. I remember hnbadges was a…
- USUsing stylometry to find HN users with alternate accounts2022 · stylometry.net · ▲676
Author here. This site lets you put in a username and get the users with the most similar writing style to that user. It confirmed several users who I suspected were alts and after informally asking around has identified abandoned accounts of people I know from many years ago. I made this site mostly to show how easy this is and how it can erode online privacy. If some guy with a little bit of Python, and $8 to rent a decent dedicated server for a day can make this, imagine what a company with millions of dollars and a couple dozen PhD linguists could do. Here's Paul Graham:…
- NANextDNS Adds "Bypass Age Verification"2025 · ▲537
We just shipped a new feature in NextDNS: Bypass Age Verification. More and more sites (especially adult ones) are now forcing users to upload IDs or selfies to continue. We think that’s a terrible idea: handing over government documents to random sites is a huge privacy risk. This new setting workarounds those verification flows via DNS tricks. It’s available today to all users, including free accounts. We’re curious how the HN community feels about this. Is it the right way to protect privacy online, or will it just provoke regulators to push harder? https://nextdns.io
