How do you change opinions using that? Would it be an illegitimate way to change someone's opinion?

I think what they're describing are propaganda bots. If so, what you're asking is how does propaganda work, and is it not legitimate?

[Bromskloss]

Yes. Voting patterns, for example, how do those change people's opinions? It would seem that the most they could do is give an impression of what comments are and are not well received. Do people base much of their opinions on that? In which direction?
