Youtube Comment Rater-VoteUP Bot

I would like a program that vote up a comment by youtube user on youtube. The only thing the bot does is "Vote up" comment, nothing more. "Voted up comment" must be in top comments on youtube-THAT IS THE MOST IMPORTANT. I would like to input a list of Youtube Video URL's and the Username of the of the User who has already made the comment that we will be Upvoting. We will then input a list of YouTube Usernames and Passwords and also some Proxies that the accounts will use. The process is simple, the bot uses a one of the Proxy I.P's and logins into one of Youtube Accounts, goes to the Youtube Video URL and UpVotes a Comment by a User, logs off and then does the same with the other Youtube Accounts. P.S I will need your commitment that you will debug and improve the software should Youtube block the software from working. I dont want to use the program then one week later Youtube blocks it from working!Since Youtube change costantly, please don't bid if you haven't programmed something similar in the last months, because it's MANDATORY that you are familiar and knows how to overcome recent Youtube limitations and spam filters. That's also why I've been so concise, you must know very well the Youtube system and his basics to bid on this projects. So, I will take in consideration your application only if you will show me previous similar YT bots recently completed through PM. I'd also like to know your price for future updates.
