In Russia, sharing the number "666" on social networks can sometimes be considered problematic by law.
It is reported that such symbols are associated with the ideology of certain groups recognized as extremist and banned in the country.
Medianews.az reports that court documents show the number 666, pentagram, and the depiction of Baphomet as characteristic symbols of that movement. Baphomet is usually depicted as a goat-headed figure with a pentagram on it.
The information also notes that administrative measures can be taken against persons sharing such symbols. For example, one person in Tyumen was fined for spreading such depictions on social networks, and in Tomsk, a person with a 666 tattoo received an additional administrative detention penalty.//Milli.Az
