As most of you know (hopefully), anonymous editing on mobile has been enabled for all projects (except Korean Wikipedia). One of the side effects of this is that there has been an increase in vandalism that uses emoji (https://en.wikipedia.org/wiki/Emoji
). Much of this vandalism is not caught by existing AbuseFilter filters. I encourage all projects to add new AbuseFilter filters for detecting emoji, and either showing a warning or preventing such edits.
The Unicode range for all emoji characters is [🌀-🙏🚀-🛳☀-➿], although you may need to customize this for your particular project. For example, the emoji characters ★ and ☆ are commonly used in Japanese song titles.
