Hello.
I've understood your requirements and it is fairly accessible to code. I wonder if you want this bot also to create accounts before viewing the video (The accounts won't need to be verified, so the bot can have some identity while viewing the video).
I suggest using C# to create the bot, as it is fairly easy to control and debug the view counter.
As for my experience, I come from another freelancer website (ELance), where I've been doing bots/crawlers/scrapers for quite some time now. I've made bots for Twitter, Tumblr and especially facebook (without any API).
My main programming language is Python, but I'm fairly proficient with C# (I code daily in it).
I'm looking forward to hearing from you.
With my best regards,
Tiago
