That criticism seems to have already been borne out. This week alone Roskomnadzor has closed down, among others, a Wikipedia-like encyclopedia of satire, which contained an article about how to make hemp (often associated with marijuana) soup; an online library, which included a copy of "The Anarchist's Cookbook," a 1970's American-authored manual for radicals; and a popular torrent-tracking website, on which users had apparently exchanged a file called "The Encyclopedia of Suicide."
The agency allowed those websites to reopen after the "offensive content" was pruned. But experts say those examples were hugely popular websites whose closure attracted immediate public attention and a storm of complaints; restoring service may not prove so easy for smaller victims of the law.
"The first several days of operation of this law have confirmed our worst fears," says Oleg Kozyrev, a media analyst and popular blogger.
"Roskomnadzor can shut down a site within 24 hours, without appealing to a court. But in order to restore a resource, one has to complain and go to court. Even so, the rules for getting back online are not at all clear ... As a result, big resources like YouTube, or internet encyclopedias, or social networks are all under threat. They have millions of users, and some of them are inevitably going to post something deemed offensive. That could lead to the closure of the whole portal," which will be disruptive even if it's temporary, he says.
