Everything You Need to Know About Web Scraping

We all love reading about the brands we wear, the celebrities we adore, and fashion trends. To do that, we need to visit various websites and collect information from them. 

Web scraping also involves collecting information from websites and pages. Although it is done unconsciously, you are still scraping while surfing data. 

More precisely, web scraping or screen scraping is a deliberate action. Whether you copy text from a site or page, or write scraping scripts, you are scraping. 

Although we do it unconsciously, the question of whether web scraping is legal or not remains open. 

Which Sites Can Be Scraped?

The internet is a sea of knowledge in any field. You get access to all data available online in real time and older. But choosing which site to scrape to gather the needed information is a challenging task. You can scrape sites keeping the following points in mind: 

• Check whether the site allows crawling or not. This can be verified using the robots.txt file. It sets rules for crawlers and scrapers. If a website does not allow access, it can be scraped. 
• Some sites allow scraping, while on others this capability is blocked. 

Is Web Scraping Abused? 

Do you receive spam emails or messages from sites you never signed up for or gave your personal information to? If so, that means you have been scraped somewhere, consciously or unconsciously. You can also be caught through any of your social media accounts. 

• Web scraping is an abuse when there is an attempt to access a person's personal data through their social media handles. 
• You may not know, but when using social media, many creeping chatbots scrape your personal information. This is malicious activity. 
• Recently, Facebook reported a leak of user information, even though that information was private. 

Now let's move to the most important question, 

Is Web Scraping Illegal? 

The question of the legality of web scraping still needs an answer. However, the decision on whether it is legal or illegal depends on the nature of the site or page. If malicious actions are detected, they are considered illegal. 

The Internet & Social Law Blog detailed the case of hiQ Labs, which won a case against LinkedIn. Subsequently, the company stated that the Computer Fraud and Abuse Act only prohibits unauthorized access to users. The judge ruled that since data on LinkedIn is publicly available, web scraping from LinkedIn is allowed. 

Not only that, but various court cases raise the question of whether information posted on social networks can be accessed or not. Additionally, questions arise about the privacy policies of these sites and social networks. This is because they guarantee complete data privacy. 

Are Web Scraping and Hacking the Same?

• Although hacking ultimately leads to data theft, web scraping is different from hacking. 
• Unlike hacking, scraping uses specialized scraping tools. 
• Hacking involves unauthorized access; web scraping only targets data visible on the front end. 

Conclusion 

With the right approach, web scraping is not illegal. Scraping is necessary because: 

• You get access to a large amount of data 
• It expands your scope of activities and improves technical coding skills. 

Therefore, instead of abusing the concept of web scraping, it's better to use it for your own development.
