Several types of paywalls exist, such as "hard" paywalls, which completely block access without a subscription, and "soft" paywalls, which offer limited access or allow users to view a certain number of articles before requiring payment. Tools designed to remove paywalls exploit loopholes in these systems, such as manipulating the site's code, using browser extensions, bypass paywalls or accessing cached versions of the content.While some argue that these methods democratize access to information, especially for those unable to afford subscriptions, others view it as a form of piracy, undermining the revenue model that supports journalism and content creation.
