[Edited to add: I don't know any of these people, fashion, or anything. I'm however extremely skeptical of conspiracy theory talk, poorly-contextualized information, and so need way more than context-free photos allegedly from an instagram page.]

No way.
To be clear, I just don't think they're any more edgy than what is already normalized. It's just easy to prime the brain into thinking it's more serious than it is, because it's being put into an ominous context. In reality, simulated murder and children in one-pieces are already normalized as popcorn-level entertainment in the context of tv shows and gymnastics. If this is bad then we should really be cracking down harder on way more stuff than an instagram page.
As for Volkova, I don't know enough to judge, but you might be right, I don't know; but it's a separate issue, in which there may be more under the cover than the usual insinuation and conspiracy thinking.
