Exclude admins and moderators from character count limits and word ban in WP Chat

1. If the "Blocked Words" option is enabled in chat settings, those "banned words" are replaced for all users, including admins and moderators. How can we exclude mods and admins from it?

2. Moderators (admins and mods) are affected by the message character limits the same way as other users. How can we exclude them from this limit?
