Aliasing moonspeak → invalid_tag
Link to alias
Reason:
Not a valid tag. non_english was already aliased away to --> invalid_tag. moonspeak is just a more pejorative term for the same thing, with the added problem of being sometimes used for trolling. Aliasing it away would handily prevent any future/continued misuse intentional or otherwise.
If a language is in the image, it should be identified, tagged with the appropriate language tag (spanish_text, japanese_text, etc) so that it can be easily searched for, translated, blacklistable, etc. Tags like moonspeak or non_english aren't needed or even that useful.
