According to Artem Kozlyuk, founder of Roskomsvoboda, says even the owners of blacklisted websites usually don’t know why they have been blacklisted, so only by suing Roskomnadzor they can find out the reason. Website hosting services, which are obliged to block banned websites, also only know about the fact of blacklisting: the only information publicly shared is the number of a decision and the article of law, Kozlyuk told CoinDesk.
