Reply To: WordPress Author Enumeration Bot Probe Protection – Author ID, User ID

thought I’d share what has worked best for me, works with multisite networks & ‘domain mapping’ =)

# BEGIN AUTHOR ENUMERATION PROTECTION
RewriteCond %{REQUEST_URI} !^/wp-admin [NC]
RewriteCond %{QUERY_STRING} (^|&)author=([0-9]){1,}$ [NC]
RewriteRule ^ /? [R=301,L]
# END AUTHOR ENUMERATION PROTECTION
