I would argue more generally that censoring words like this is unhelpful and counterproductive.

As seen in the link in the post body, not only can it inhibit clear communication, but anyone actually using the slur would be more clearly identified if the slur remained - thus allowing the mods to definitively identify the user as bigoted and banning them. Replacing it with ‘removed’ creates ambiguity in combating bigotry as well as edge cases and discussions of words - as in the linked case.
