> just ask anyone who runs a more popular site The person you're responding to already said they ran a modestly sized site. What actual scale opens one up to abuse? If only the top 1% of sites need it, then it seems silly to say "everyone" needs it.

So everyone is paying cloudflare… why?

Because paying with MITM is far less visible than paying with money

You get downvoted for these opinions but I agree. Most people that complain that their servers get hammered by AI bots are those that run very unoptimized servers that can only handle like 100 rps. I've never had any issues with any of my moderately optimized websites. A $10 VPS can handle sooo much traffic.

I think people get annoyed when it's suggested they spend time optimising or even re-writing their websites to handle high traffic loads just to cater to AI bots ripping their content. It's also not always easy to do. I run a small wiki which is fairly optimised, nearly every page manages at least ~3k rps on a small VPS. The only exception is the diff page which is ~150 rps. Optimising that while still giving good ou…

There really isn't a good reason for a wiki (or git host) to provide diffs between arbitrary revisions to unauthenticated users. Limit it to diffs compared to previous (which can be cached) and this problem goes away.

In any case, such labyrinths of expensive dynamically generated pages are no excuse for subjecting people requesting the start page to bot checks.

Why not block all odd v4 addresses while you're at it? I heard that that can reduce scraping volume by 50%!

That's harder to set up, and also unfair to people who have an odd IP address. It's easier and better to just block 0.0.0.0/1 half of the time, and 128.0.0.0/1 for the other half of the time. Switch every day at noon. Bot traffic will be cut by 50%, and humans are all treated equally! It's a total win!

And blocking ipv6 addresses isn't unfair to people who have an ipv6 address?

The bot I had was using unique IPs for each request. Some were from cloud providers but most were just random residential ISPs. I couldn't see any obvious connections so rate limiting would've had to be a global rate limit. Similar to the one SQLite had: https://www2.sqlite.org/forum/forumpost/7d3eb059f81ff694?t=h Each IP only makes ~1 request though so easy to detect after the fact. I guess they will run out of IPs…

You were getting 1k rps, and each request was from an unique IP? So after an hour you got hit by 3.6M different IPs? And all from uncorrelated /16s? That seems hard to believe. Not that I don't believe you, it's just hard for me to grasp that whoever was scraping you had such a large and distributed swarm.

This is called rotating residential proxy service. You can buy it off grey market sites that are probably getting it from botnet operators. It costs about $2-$5 per GB.

The problem is what is the alternative? I'm (not) defending them or this practice by any measure, but we all know what happens if you just open your site up without these, especially with AI bots which hammer servers and are in effect a legalized DDoS system. I've hated CAPTCHAs ever since I first encountered them and I can't wait for them to just finally die a permanent death, but I also don't know how we solve the…

I think there's some chance we get a "proof of purchase" system where there is some entity that takes a $10 payment to give out a unique identity token that you need to present to visit most sites. if you have a revocation process for ones used for bad actors, it seems like it would work pretty well.

That's called an IP address. You pay your ISP $50+ every month to get one. Has it worked so far?

I don't think it's just privacy, it also increasingly turns the web itself into a walled garden. The end result is that websites can only ever be accessed by "approved" clients - the latest Chrome, Edge, Safari and if you're lucky Firefox - and nothing else.

> and if you're lucky Firefox I haven't had any problems with Firefox so far. Why do you say this?

It's already a problem with Firefox + some essential web condom extensions.

Cloudflare is known to use fingerprinting to detect scrapers For example, they use JA3 fingerprints and match them against the UA to block stuff like cURL while allowing OkHttp (Android clients) - but this can be easily be spoofed with packages such as CycleTLS [1]. I don't want to defend them, because they gate away a good chunk of the internet with their "bot protection", but unless you do PoW (which is also ecolog…

PoW doesn't fix anything if you have an army of zombie CCTV cameras and smart fridges at your disposal.

It's either proof-of-humanity (increasingly hard to get in this day and age, particularly if accessibility is a concern), proof odf identity (even worse) or proof of system integrity, which is the least bad out of all the terrible options.

"Your browser appears suspicious because it looks like you are trying to hide your identity" Another case of the much predicted downfall of freedom due to "people who hide themselves must have something to hide, so they are automatically suspicious"

CF business model heavily relies on fearmongering, so what we can expect? They send these emails you know? "CF saved you XXX Gb of data and protected your from YYY attacks". I have few high load web sites which I turned CF on for a while. Knowing my traffic pretty well, I can say these "CF saved you XXX Gb of data and protected your from YYY attacks" is absolute bullshit with numbers greatly exaggerated. Since wwe ca…

I can only assume that every time I back out of these sites because I don't want to check the box or just don't want to wait a few seconds that is marketed to the site owner as a GREAT VICTORY as I am clearly a EVIL BOT that they have defended the site from.

I'm one of those who have enabled cloudflare on all of the sites I maintain. Additionally, Added turnstile on every form. I know some actual users get blocked. But the amount of spam we get without it, the amount of bot traffic simply overwhelming the server... It is just too much. Recently I also hard blocked all IPs from china Singapore India Pakistan Russia and whole of africa. Do I want to do it? No. But the amou…

[flagged]

Actually you are. It's called living in country. Lawless countries don't get blocked. If you don't like it, clean up your country.

> Firefox added profile switching recently. I think this was as recent as 25 years ago? Recently they added some new UI. There was and still is (I think) classic Profile Manager UI, which you can launch with ./firefox -ProfileManager or access UI in about:profiles. But you don't have to use any of those anyway - see my comment above (a response to parent).

The old UI was pretty difficult to use, and hard to discover unless you knew where to look though.

What about the old UI is difficult to use? I am assuming you are talking about the profile manager.
