Another example: on one of facebook groups I regularly see posts from a person regularly bashing Russia. Under every post he leaves derogatory comments. Sometimes he posts derogatory posts although the facebook group is not about Russia at all.

Just recently he had shared a meme picture from some of the "opposition" groups (Alexei Navalny or his friends) stating that Russia has the highest suicides rate in the world (of course, because we're poor and doomed and Putin eats our children for breakfast).

I didn't believe it and went to several official sources (including international) to verify. Of course, we're very far from the first place in the list of suicide rates. I've commented this on the post and received zero reaction. Moreover, the post was liked and shared further by several members of the group.

This is all you need to know about our "opposition".

And there're many persons like this disseminating fake news in facebook groups and other communities. I have no evidence, but I strongly believe that they're on a payroll from some non-Russian agency or NGO.
