Currently, we have the policy of using the contact form to report sites scraping our content.
However, if we go to the contact us page link on the bottom of the page, there is no option under "What can we help you with?" indicating that we can do this, aside from selecting the "Other" option, nor is there a Help Center topic about this: https://anime.stackexchange.com/help/search?q=scraping
For an experienced user, this might not be a problem to search meta for this, but this might confuse new users as to what they can do when they find a site scraping content from Stack Exchange. At the very least I would like to request a new topic be added in the contact form about this.
