I think that would defeat the purpose of censoring if people knew which exact swear word was said, since swearing is against chess.com's tos.
Mods/Staff already censor in a way I believe is good enough; they usually leave a reason why something was removed and sometimes even include link(s).
Instead of removing a word entirely and replacing it with "[Removed - MS]" for example, how about you add a few letters for context, like "f[Removed - MS]".
