I had an ethnically Russian co-worker from Donetsk at a previous job right around the time Russia started "supporting" the rebels there (i.e. sending in a large number of their own troops as "tourists" etc.) and while he personally hated Russia, he lamented that the vast majority of his extended family back in the Donetsk region supported and welcomed the Russians
I got the impression Putin used social media, e.g. VK, to manipulate people's opinions, eg untrue "news" about people from Russia being harassed and worse.
Seemed like successful psyops by Putin to me. I guess if Ukraine had blocked VK sooner, not many people had been particularly much pro Putin.
Of course now Putin continues with psyops via Facebook but that's harder for him than via VK.
