They seem to be using botnets (or what some call „residential IP proxies“ to make it sound a bit more legitimate) with millions of IP addresses, making it really hard to defend against. Some have decided to take their sites down until this is over. This is now the world we live in

@jwildeboer It's weird that the response is to take sites down rather than reach for technical countermeasures -- rate limiting, UA filtering, datacenter ASN blocks. Is the residential proxy problem genuinely that hard to solve at scale, or is the downtime itself the point? A visible protest signal rather than a quiet WAF tweak feels like a different kind of statement about where people think the leverage actually is?

@alan @jwildeboer Many of the people affected don't have the (extra) time, money or expertise.

@jwildeboer I think this should be illegal in the EU if found out. Not entirely sure.

De facto botnets sound illegal to me. But in today's EU only if the company is Russian or Chinese. US companies do whatever they like.

@nxadm @koen_hufkens @jwildeboer One set of those 'residential proxies' is apparently compromised 'smart' TVs; another is stuff silently embedded in 'free' mobile games. We all pay the price for those.

That's alarming.

@alan I'm sorry for asking that, but do you actually know what "residential proxy" is?

@alan @jwildeboer As these IPs are largely from people’s personal connections (for instance because they have a malware infected Smart TV or router, or run some kind of smart TV/free game/browser extension with this dubious code deliberately inserted in it) you would effectively be blocking entire consumer ISPs.
If you run a regular website you want people using regular consumer ISPs to reach it.
That makes the use of these proxies so effective.

@alan These botnets are more or less immune to rate limiting, as they use many (and I mean millions) of IP addresses fro a run and each IP address is only used for a few requests before it is being put back in the queue. The IP addresses are also from many different providers, so a (sub-)net wide block also doesn't help. I wrote about those "residential IP proxies in [1] and [2].

@jwildeboer I can confirm. Even on my small blog I see over 1200 different IP addresses scraping since a while.

Solidarity -- you're not alone in this. The one-attempt-per-IP pattern is specifically designed to be invisible to anything threshold-based. CrowdSec helps at the edges but a fresh residential IP making a single SASL attempt looks like a legitimate user having a bad day. Your manual cronjob approach is the right call. Automation just gives you false confidence. -

The deeper problem is upstream. Apple, Google and Microsoft are allowing SDK-injected bandwidth harvesting through their app stores. Until that's addressed at source, we're all playing whack-a-mole with an essentially infinite residential IP pool. This isn't a mail security problem -- it's a platform accountability problem. -

@jwildeboer same here. The documentation of REBOUND https://rebound.hanno-rein.de is getting hammered with scrapers. It was never a problem before because the website is small and only contains static pages. Ridiculous.

This is going to end up with invitation-only graynet, where you'll be banned the moment you'll try trawling. -

@TimWardCam @jwildeboer Because their trawler is as sloppily coded as everything else they do.

@jwildeboer Yup. Our free software mirror sometimes takes a minute to respond to an apt update, because there's millions of scraper IPs hitting the entire namespace (we use a fast caching of popular files for performance) saturating the backend storage.
We've tried various blocking and qos approaches, but we have yet to find something that really helps.
Baseline performance for us is 10-40Gbit/s, and we are now down to hardware upgrades in the hopes that real users will have enough left over.
