TL;DR
Residential proxies continue to be a major tool for web scraping, with criminal and semi-legitimate operators exploiting compromised devices. The problem persists despite efforts to mitigate it, raising concerns about web security and data privacy.
Recent developments confirm that residential proxies are still widely used in web scraping operations, which is discussed in our update on residential proxies and the scraper situation, complicating efforts to protect websites from automated traffic. Despite some takedown actions, the activity persists, with malicious actors leveraging compromised devices and semi-legitimate companies offering proxy services to scrape data at scale. This ongoing situation highlights the persistent challenge of controlling unwanted web traffic and protecting content. You can learn more about the current landscape in our update on residential proxies and the scraper situation.
Over the past year, the problem of web scraping using residential proxies has grown more complex. Attacker-controlled networks often use malware-infected devices or poorly secured streaming gadgets to generate vast amounts of traffic that mimics human behavior, making detection difficult. Google’s shutdown of the IPIDEA bot network earlier this year temporarily reduced scraping activity, but the activity has since resumed at high levels.
Operators like Bright Data promote their proxy services as “ethical” or “legitimate,” offering users the ability to route traffic through their devices, effectively turning them into proxy endpoints. For more on this topic, see our article on residential proxies and the scraper situation. These services often advertise their ability to bypass website restrictions and traffic limits, raising concerns about their role in facilitating large-scale data extraction. While some companies explicitly state they do not use these proxies, it remains unclear whether major AI training firms are sourcing data from such networks.
Experts warn that these proxy networks can be exploited for purposes beyond scraping, including spying or launching targeted attacks, given their access to vast and diverse network resources. The use of these proxies by shadowy government agencies or covert operations is suspected but not confirmed.
Implications of Residential Proxy Use for Web Security
The continued use of residential proxies in web scraping poses significant risks for web security and content creators. It complicates efforts to detect and block malicious traffic, enabling large-scale data theft, content scraping, and potential cyberattacks. The rise of semi-legitimate proxy services also blurs the line between ethical data collection and exploitation, raising questions about accountability and regulation.
This situation underscores the need for improved detection methods and stricter policies to safeguard web resources and protect intellectual property. The ongoing activity also threatens the integrity of AI training datasets, which are increasingly sourced from the open web without clear oversight.

Background on Proxy Networks and Scraping Trends
In early 2025, reports highlighted the growing use of residential proxies by malicious actors to evade detection while scraping websites for training data and other purposes. These proxies are often operated through malware-infected devices or poorly secured consumer electronics, including streaming devices. Companies like Bright Data have marketed proxy services as legitimate, offering users the ability to monetize their devices’ network connections.
Earlier efforts by tech giants such as Google to dismantle bot networks like IPIDEA temporarily reduced scraping traffic, but the activity has since rebounded. The problem is compounded by the difficulty of distinguishing between benign and malicious traffic, especially as attackers mimic human browsing patterns. The debate over the ethical and legal use of such proxies remains unresolved, with many companies and researchers expressing concern over their unchecked proliferation.
“Proxy services marketed as ‘ethical’ are often used to mask malicious activity, making detection and regulation challenging.”

Next Steps in Monitoring and Regulating Proxy-Driven Scraping
Industry experts anticipate increased efforts to improve detection techniques for proxy-based traffic and stricter regulation of proxy providers. Law enforcement and cybersecurity agencies are likely to continue investigations into malicious networks and their operators. Meanwhile, website operators are exploring advanced anti-bot measures and traffic analysis tools to mitigate ongoing scraping threats. Transparency from AI companies regarding their data sourcing practices is also expected to become a critical focus.

Key Questions
Are all residential proxies used for malicious purposes?
No, many residential proxies are used legitimately, but a significant portion is exploited for web scraping and malicious activities, often without device owners’ knowledge.
Can websites effectively block proxy-based scraping?
Blocking proxy traffic is challenging due to the diversity and volume of residential proxies, especially when they mimic human browsing patterns.
Are major AI companies using residential proxies for training data?
It is currently unconfirmed whether leading AI firms source training data from residential proxy networks. The practice remains under scrutiny.
What measures are websites taking to defend against proxy-based scraping?
Websites are deploying advanced traffic analysis, CAPTCHA challenges, and behavioral detection methods to identify and block suspicious activity.
Will regulation or legislation address the use of residential proxies?
Regulatory efforts are emerging, but the complexity of proxy networks and privacy considerations make comprehensive legislation challenging.
