Prohibited Emoji 🚫

What 🚫 means

A red outlined circle with a slash or oblique of the same color stretching from the top corner to the bottom. On some platforms, this emoji is shown with a white background.

The 🚫 Prohibited emoji signifies prohibition as the name suggests, along with related themes such as restriction and banning. Although usable in similar contexts as ⛔ No Entry, this emoji would suggest a legal tangent to the otherwise casual 'entry restriction'.

How and when to use it

Generally, 🚫 can be used as a way of responding with a big, fat, "NO" - "Not happening 🚫" or "I told you already 🚫". This applies even in common contexts of rejection - "List of those who didn't make it 🚫".
Prohibition represents an official ban on certain commodities. Hence, 🚫 may be used to refer to anything that is stringently banned or even a highly exclusive area.
Some instances for the previous point - "Staying home for the next few weeks, practicing self-quarantine 🚫" or "Kids Not Allowed 🚫".
🚫 could also act as an alert or an alarm for mostly negative or cautionary frameworks. For example, "Do not refresh the page before confirmation 🚫" or "No entry to the contest without registration 🚫".
If you're sharing newsworthy posts or reposts about a legal ban, 🚫 is a must. Like, "Alcohol sale banned in these states 🚫" or "Here is a list of strict DO NOTs this New Year 🚫".
