Subversion of norms, yes. But it's also meant to communicate other things as well.
Yandex has all sorts of wonkyness going on. The JB images that spammer-anon posted a month or so ago all were searchable in Yandex. The source of a lot of these images were child modeling agencies, which (if you dig far enough) leads you to an elaborate CP trafficking network. The sites where a lot of the more explicit content is regularly hosted on honeypots on the DW, which no one seems to know if they belong to white hats or dark hats.
A promising sign is that many of those sites are going offline, one at a time. They go through cycles of being online, then are taken down. Then, eventually, they come back online again. This leads me to believe the White hats are running them. Helps this anon rest a little easier to know the white hats are in control.
