Launched rename.world - a site where people rename world geography and vote on it.
Week 1 stats: 1k users, 30k renames, 100 billion (!) database reads.
That last one was a bug, the query looked fine, worked fine, but D1 charges per row scanned. Woke up to a scary number. Fixed it same day but paid for the lesson.
Other highlights: someone renamed half of Belgium to "Profondsart" overnight. That word is now permanently banned. Also got a spam attack that trashed the whole map with slurs while I slept. Restored everything by wiping the attacker's account, turns out requiring sign-up was a good call even though people complain about it.
Despite all this it's been fun. Didn't expect much from a joke project but people seem to actually enjoy it. Let's see where it goes.

Site: rename.world
A simple, memorable name builds strong brand identity and improves discoverability. Focus on clarity, relevance, and uniqueness so users instantly understand your value and can easily recall and share your product.

Sounds like a fun time. Interesting to see what people do lol.

100 billion reads? Ouch. That’s a legendary 'launch tax' right there. Glad you caught it before it got worse!
The 'Profondsart' incident is hilarious, but the spam attack sounds like a nightmare. It’s a great reminder that friction (like sign-ups) is often a necessary evil to protect the product's integrity.
I’m currently building Bossr, a video-first hiring app, and my biggest fear is exactly what you described - someone uploading 'garbage' or slurs instead of real content.
Question for you: Now that you've seen the scale, are you planning to add some sort of automated moderation/AI to flag slurs, or will you stick to manual 'wiping' of accounts?

The D1 billing gotcha is a classic — row-scanned pricing is one of those things that looks totally fine in development and then explodes at scale. Good on you for catching it day-one rather than month-end.
The Belgium/Profondsart incident is genuinely funny. There's something very internet about one person methodically renaming an entire country overnight. The fact that requiring sign-up saved you from the spam attack is a great data point — I've seen too many projects skip auth to reduce friction and then get wrecked by abuse.
30k renames in week 1 from map communities on Reddit is strong signal. The "joke project that people actually use" is how a lot of successful products start. Wikipedia was arguably a joke project too.
Do you plan to monetize it? If so, how? :) thanks
Maybe hide/show NZ was going to be the premium tier. I'm giving away the killer feature for free right now

That’s the question! Really, how? Donations not working on that level, I wish I had a plan, but currently just developing features for fun

Congrats on the wild first week! Those "woke up to a scary number" moments are rites of passage for sure.
Your spam attack recovery story hits close - it's that exact "while I slept" vulnerability that keeps B2B/enterprise founders in compliance-heavy industries up at night.
Quick question from someone in the compliance/automation space: At what user/threshold point do operational risks like data integrity attacks, audit trails, and recovery SLAs start keeping you awake? Is it a user count thing, a revenue milestone, or just the first time something breaks?
Love the transparency on both the bug cost and the sign-up trade-off. That Belgium rename saga is hilarious and terrifying at the same time.
Not a user count thing, it started the first time stuff broke while I was asleep. If I can't tell who did what, limit the damage, and undo it fast, I'm not sleeping, so I’m building logs, rate limits, quick rollback before chasing more growth
Your "logs, rate limits, quick rollback" stack is basically a compliance foundation in regulated industries. When you can't trace who did what, limit damage, or undo fast, you're not just losing sleep - you're risking fines, failed audits, and legal exposure.
Here's what I'm trying to map out for our compliance automation layer:
What specific "can't sleep" scenarios actually trigger companies to build (or buy) these safety systems?
Is it:
1. First security incident? (like your spam attack)
2. First enterprise contract requiring audit trails?
3. First regulatory deadline they might miss?
4. First time data gets corrupted and they can't restore?
5. Something else entirely?
Your real-world threshold (breaking while asleep) is exactly the kind of trigger moment we're studying. Any other "now we MUST solve this" moments you've seen or experienced?
The D1 row-scanned billing gotcha is real pain — had a similar surprise with Cloudflare Workers KV once. Smart move requiring sign-up though, it's the simplest anti-abuse layer and clearly saved you during the slur attack. 30k renames in week 1 from a "joke project" tells me you hit something people actually want to play with. Curious if you've thought about leaderboards or daily rename challenges to keep people coming back?
We have leaderboards already and some new cool mechanics on the roadmap!

The “100 billion database reads” statement certainly drew a chuckle and eye-roll from me. ~
I know precisely the moment you are referring to when everything is okay, everything is working fine, and then the bill comes in. It is a reality learning can be paid for.
Users are getting quite chaotic as well. The overnight renaming of half of Belgium and the slur spam attack is as good a stress test as any public facing project.
It’s impressive how you immediately fixed things up, added sign up, banned some words, and moved on. The week one story is a lot more interesting than a funeral smooth launch.
How/where did you announce it initially?

Customer acquisition breaks down when it’s treated as a content problem instead of a timing problem. In healthcare especially, buyers don’t announce intent with “who should I buy from?” mostly describe friction like documentation delays and compliance anxiety.
Those conversations are already happening in public threads, long before anyone books a demo. With AI home health software, the decision often starts when someone asks how to reduce admin load or prevent errors.
