Law enforcement in Russia works differently than in the US, especially in politically charged fields. An exapmel: in the US, one man was charged of breaking construction codes because he was doing chemical experiments in the basement of his single-family house, in a block zoned accordingly.
I understand this is extreme, but a good illustration. He was doing something on his own, and was charged. Such enforcement is extremely unlikely in Russia even in todays situation. For instance, a recent law explicitly banned _searching_ for extremists materials, e.g. Navalny's party website (they're labelled as extremists ex-court by the Interior or the Justice ministry, I don't remember). But there's been just 1 court case since then. You can search whatever you want as long as you're not public about it. As soon as you get enough publicity, you do get on the radar.
Same kinds of examples: in the 1950's USSR some musicians were shadow-banned (there was no legal ban on them), and not published. A man made a lathe and carved disks with their music on used x-ray films. He was arrested when he got enough publicity and sold good deal of copies. He was charged not for copying them -- there was no ban on this -- but for illicit enterpreneurship, or speculation as it was called back then. Had he been doing this alone, he'd probably have not got under arrest.
I actually, think it's roughly the same as dealing with Torrent and trackers in the Western world nowadays.
