Symbols for no, forbidden Emojis

There are surprisingly many symbols, which forbid one or other activities, in the standard emoji set. From the No Smoking sign to a Red Cross mark, which can be used for literally anything. For a less aggressive prohibition, use a black cross (which is also a multiplication sign), or a solid white circle, which looks quite delicate and diplomatic.
