What's the problem. The Russians do stuff that you say are "war crimes", and what happens to them? Nothing. So why should anyone care if some person on the internet says these are war crimes? There's obviously no penalty against doing them, so they're not really war crimes.
Remember that war crimes were defined to protect civilians. It's usually better for a civilian to be on the losing side in a war with no war crimes, than the winning side of a war with many war crimes.
