i tend to use tor network as a proxy which enables me to request a new ip whenever i need
quite slow and often blacklisted (by Cloudflare for example)
of course no option if your 'target' blocks tor ips
Advanced scrapers mostly use residential IPs nowadays, but there are some services to detect those too, e.g. https://focsec.com/
This is relatively easy to block, given that these companies publish their IP ranges. Similar to the Tor block, blocking "datacenter IP's" simply becomes the norm. This is why you have companies offering "resi's" or residential proxies to bypass such blocks for some years now.

I heard a while back, on HN 8 I think, that a lot of residential proxies are computers that have been infected with malware. How true is that?

Is it ethical to scrape things, trying to bypass prevention methods, against the expressed wishes of a site?
They follow links that are explicitly marked as do not follow, they do not even try to limit their rate, they spoof their user agent strings etc etc. These bots cause real problems and cost real money. I do not think that kind of misuse is ethical. In fact, using this tool to circumvent protections can turn your scraping into a DDOS attack, which I do not feel are ethical.
If your bot behaves itself though, public information is public imo. Just don't take down websites, respect rate limits and do not follow 'no-follow' links.
To give an idea of the size of the issue, we have websites for customers that have maybe 5 hits per minute from actual users. Then _suddenly_ you go to 500 hits/minute for a couple of hours, because some bot is trying to scrape a calendar and is now looking for events in 1850 or whatever. (Not the greatest software that these links are still there tbh, but that is out of my control.)
Or another situation, not entirely related, but interesting i think: A few years back for days on end 80% of our total traffic came from random IPs across china & request could be traced through HTTP referrers where the 'user' had apparently opened a page in one province, then traveled to the other side of China and clicked a link 2 hours later.
All these things are relatively easy to mitigate, but that doesn't make it ethical.
From what I've seen the cloud IPs are the first to get blocked by anti-scraping tech.
e.g. Built an amazon scraping thing at home. Worked fine. Deployed to cloud. Literally first request Amazon goes nope you're a bot

Are there even ethical or “official” ways to source residential IPs? I thought most of them were from botnet infected IoT devices.
