According to Dancho Danchev, there's an elegant solution out there, just waiting to be bought and implemented: a software tool that uses API keys offered by a CAPTCHA-solving services to automate the account registration process (click on the screenshot to enlarge it):
Apparently, the bot can create up to 30 accounts at the same time, it can upload videos, logs activities and more.
"What’s particularly interesting about this tool is the fact that every automatically created bogus account starts following another automatically created bogus account, leading to a self-serving, potentially fraudulent segment of fake users who will inevitably start commenting and liking each other’s videos in an attempt to artificially increase their popularity, thereby undermining YouTube’s reputation-based system," shares Danchev.
The price for such a handy tool? A trifle: $20 for two months, $40 for a lifetime.
The tool apparently uses the services of two managed CAPTCHA-solving services - of which one is currently offline - and the user is expected to pay for solved CAPTCHAs via in-tool credits. 5000 solved CAPTCHAs will cost you $7, and for 100,000 solved CAPTCHAs you'll need to fork over $140.
