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 [π-ππ-π³β-βΏ], although you
may need to customize this for your particular project. For example, the
emoji characters β
and β are commonly used in Japanese song titles.
Feel free to steal the filter currently in use on English Wikipedia:
