These messages read a bit unnaturally:

• Flow-post-moderated-toggle-hide-hide: Hide comment {{GENDER:$1|hidden}} by $2
• Flow-post-moderated-toggle-delete-hide: Hide comment {{GENDER:$1|deleted}} by $2
• Flow-post-moderated-toggle-suppress-hide: Hide comment {{GENDER:$1|suppressed}} by $2

This is especially weird for the first message - it says "hide" twice.

It can be something like "Hide the comment ... again".

Another option would be to remove the name of the user who did the previous action if it's not essential.
