However, if you are doing web scraping for personal gratification then it may well be termed as intrusion into one’s personal data. For example, if you are hacking into the database of a university to steal the academic articles and using them in your own project. Any such instance is definitely an act of stealth and may accompany relevant punishment. Concisely, to get hold of someone’s creative work for individual gains is unethical.

2. When you publish scraped content:

This is yet another condition that may delve you into violating the right of the copyright holders. If you are only scraping the content for fair use, it may be permissible. However, companies often hold all the publishing rights and may file suit against you if you publish their data without their permission.

Remedy to illegal web scraping

Despite running the apprehensions of getting identified, unethical web scrapers deter to steal data from websites. Hence, the web owners themselves need to be alert enough not to fall prey to such fraudulent activities. Indeed, it is your data and you won’t like it to get compromised at any cost. Just like there are many web scraping tools available online, you can also opt for applications that offer protection against web data extraction as a fruitful remedy. These software safeguard your website content from hacking attacks such as bots, denial of service, brute force, session opening and transaction anomalies, and more.

Summary: Technology has two facets – good and bad. It depends on us which one to adopt; the same holds in the case of web scraping as well. We should make sure to use this innovation for the benefit of society and not to steal away some one’s creativity, which is indeed unethical and at times, illegal
