Filter Suspicious Queries blocks suspicious URI, query string, user agent, and referrer patterns by default. Hostname reverse-DNS matching (the blocked-hosts part of the 8G rules) is off by default because it can trigger DNS lookups and false positives on normal browser visits.
Use this filter only when you understand the tradeoff and need hostname-based matching again.
User-facing context: Filter Suspicious Queries.
Enable hostname checks
add_filter( 'secnin_cf_check_blocked_hosts', '__return_true' );With the filter returning true, blocked-hostname matching runs again. Customize the hostname list with blocked_hosts_items.
Disable explicitly (default behavior)
The default is false. You normally do not need a filter unless another snippet already forces hostname checks on:
add_filter( 'secnin_cf_check_blocked_hosts', '__return_false' );Not sure how to add this code? See Add custom code to your website.
