What is unethical about that? The video was going to get views anyway, I was just helping it out. It's like the snowball effect that would occur naturally, except they start with a bigger snowball. I don't do this stuff anymore though, that was when I was younger and in college.
I'm not saying you're a bad person. Hell, I've done plenty of unethical stuff in my time. But generating fraudulent views is a clear abuse of the system. You're simply rationalising it away.
Your assumption is that a 'clear abuse of the system' is unethical. Overflowing a char buffer to get control of EIP is also a 'clear abuse of the system', yet I have a hard time qualifying that (by itself) as unethical.
