I would like to ask if my post is what the script did. If not, I would also like to ask what it actually did do.
Yep, that's basically what it did. The bot essentially ran a imacro script that would automatically login to each account on it's own assigned proxy IP to claim the earnings. It will log into each account over a number of different browser instances, each account has it's own assigned proxy IP which is all saved in a local mysql database.
Overall the concept is fairly simple if you know how to write imacro scripts and take advantage of captcha solving services then it is pretty easy to make your own bot like this. The only problem is that the bot would only work for the sites it was specifically designed for.
