A bot is an application that automates a mission, such as setting an alarm, providing weather information, or searching the internet. Bots are ubiquitous in today's world, ranging from virus-infected bots to search engine spiders that search the Internet for new Web pages or image files to collect.
The "Anti-bot defense" function employs a variety of techniques to prevent malicious bots from reading your website's source code and scraping it for photos without your permission.
Would search be affected by this?
Search engine bots are unaffected by "Anti-Bot Protection," and Cybarmor provides an additional lock if you want to prevent your photos from appearing in search results: Search Engine Locks.
