Ukrainian situation is a complex one and brings out the worst in people, at least in post-Soviet countries. It's not uncommon for people to have different view on this issue. I know families who fight over it, people breaking up over it, it's pretty emotional subject. So with this in mind, I don't think there is some sort of conspiratorial force at work to post pro-Kremlin position on online. I don't doubt that there are paid people who spam forums but just because someone is voicing their opinion in favor of Russian official stance it doesn't mean automatic paid shill. I've been following this conflict since 2013 and I have to say that all involved sides are offenders of "their" version of events in mass media.
