The images are simply being content-blocked:

https://sun9-28.userapi.com/c813024/v813024091/64062/(censored because porn).jpg

Note that there is no warning that it's being blocked as the page loads, which lead me to wonder if they had an anti adblocker doing a window.stop() or something to cancel the image loads. We should probably not silently block images like that (I had to try setting img.src=img.src to get the above message).

At any rate, the only way around this would be to permit the images to load, or provide a stand-in so the user knows they're being blocked intentionally. Or of course we could proxy them, if we're willing to proxy porn.

Of more likely importance is that I see several potential fingerprinters/trackers slipping through strict protection, which should be reviewed:
