I have a free image host called picmecca.com. Right now, broken images are appearing in all pictures categories constantly. These images don´t seem to be uploaded by a human, but rather by a bot or machine. These broken images are pure nonsense that add no value to the site.
This project is about blocking this bot or machine, and any other external threat that may upload garbage content to the site.
You may create a [url removed, login to view] document, include bot detection codes, use captchas or similar solutions. The goal is to stop any non-human uploads from showing on the site.
You will provide your proposed idea and implement it. Solution will need to work 100%.
