Didn't have to, I could not save the code in there I only got me a 404 error. All that's there is:
# WP AUTHOR ENUMERATION BOT PROBE PROTECTION
# Rewrites to author=999999 that does not actually exist
# which results in a standard 404 error. To the hacker bot
# it appears that this author does not exist without giving
# any clues that the author does actually exist.
RewriteCond %{QUERY_STRING} ^author=([0-9]){1,}$ [NC]
RewriteRule ^(.*)$ $1?author=999999 [L]
