I'm sure there is some way to stop users from downloading files from a website, as anonymous? Downloading from a website like this, with lots of website traffic, without an account is extremely unsafe and it makes files easily downloadable and redistributable. Maybe use the CAPTCHA system when making a new account for more security? It's already used when downloading a file, so would making that for website security be effective? No one is going to be continuing using a service, like this website, if their work, is not going to be protected. Maybe a whitelisted (whitelist) method could be useful, with account validation? You know, to help stop anonymous users from downloading files and redistributing them.
