The robots.txt of Pinterest uniformly disallows access to all user-agents which are not explicitly mentioned (like Googlebot, Bingbot etc.) in the document. Specific routes like Disallow: /pin/, Disallow: /pinner/, Disallow: /search/, Disallow: /user/ etc. are specifically denied for all other user-agents. These rules clearly dictate that the essential elements of the website, like individual pins, user profiles, search results, and user-specific data, are off-limits for any web-crawling activity.

In essence, from a web scraping perspective, the robots.txt file of Pinterest does not grant permissions to crawl and scrape the site for non-listed user agents. While crawling and scraping may technically be feasible, performing such activities would strongly infringe upon Pinterest's policies and may result in severe repercussions, including potential legal actions for violation of the website's terms and services. Therefore, it's highly recommended to respect these rules and refrain from any web scraping activities.

Pinterest's terms of service explicitly forbid the use of 'automated software agents' or 'powered tools' to interact with their services including, but not limited to, web scraping. They lay emphasis on prohibiting access to the service via methods other than the interface provided by Pinterest and other explicitly authorized means that Pinterest may designate. This implies that the only acceptable way to access data would be through official, perhaps authenticated, Pinterest interfaces and not by scraping their web pages.

The terms are not flexible in their stance against violation of these constraints. Any infraction can lead to termination of the offender's Pinterest account, apart from other legal consequences. While the terms do not specify particular penalties for scraping, they maintain the right to enforce their policy in whatever manner they see fit, as well as the right to change their policy at any time. Therefore, by these terms, web scraping is not permissible in any way.
