SAC Bot's image-based anti-scam feature checks image attachments against hashes that staff have added for their server. It can match an exact image and, when a perceptual hash is available, visually similar copies. When a match is found, the bot can delete the message and apply the configured action.
This is not a general URL, phishing-domain, or text scam detector. It only helps identify images already added to that server's image list; it does not guarantee detection of new scams.
