What is that standardized way? Encrypted zip files with the password listed on the website is the easiest one that comes to mind. I wonder if googlebot will some day decrypt those files because a lot of pirated software is distributed in encrypted zip files. Scanning those files for viruses would be pretty useful for the average user. I guess captchas are the only bulletproof solution
