Sites that contain large amounts of copyrighted content (Image galleries, subscription newspapers, webcomics, movies, video, help desks), usually involving membership, will ...
security.txt is an accepted standard for website security information that allows security researchers to report security vulnerabilities easily. [1] The standard prescribes a text file called security.txt in the well known location, similar in syntax to robots.txt but intended to be machine- and human-readable, for those wishing to contact a website's owner about security issues.
