Frequently Asked Questions
Common questions about WhoKnew Shield — Email, Phone & Address Security
It protects your email addresses, phone numbers, and physical addresses from spam bots and scrapers by encoding them in a way that real visitors can still see and use (with one click), but automated tools have a much harder time harvesting. Uses dual-layer obfuscation (HTML entities + CSS reversal + JavaScript) for robust contact security.
Yes. Obfuscation is applied when the page is generated, so cached pages still show protected content. Compatible with WP Rocket, LiteSpeed Cache, W3 Total Cache, SiteGround Speed Optimizer, and other major caching solutions.
Yes. In Protection Settings you can turn auto-detection on or off for email addresses (free), phone numbers (Pro), and physical addresses (Pro) separately. Shortcodes let you protect specific pieces of content regardless of auto-detection settings.
Yes. The free plugin has no locked features. You get dual-layer security, email auto-detection, click-to-reveal, and all shortcodes. Pro adds phone and address auto-detection, Scraper Trap WAF with honeypots, IP blocking, analytics dashboard, and competitor shortcode support.
Scraper Trap is a Pro feature that functions as a Web Application Firewall (WAF) to actively catch and block bots. It uses hidden honeypots (invisible links/forms that only bots trigger). When a bot takes the bait, their IP is automatically blocked site-wide. This is active security defense vs passive hiding — it protects your entire WordPress site by identifying and blocking threats before they can harvest any email addresses, phone numbers, or physical addresses.
Yes! WhoKnew Shield Pro supports shortcodes from other popular anti-spam and email security plugins, making migration straightforward. If you're using Email Address Encoder ([encode]), Neotrendy's Email Address Obfuscation ([obfuscate_email]), Email Encoder Bundle ([eeb_protect_emails], [eeb_mailto]), or Antispambot, just activate Shield Pro and deactivate the old plugin. All existing shortcodes work immediately. No find-and-replace needed.
Manual shortcode plugins require you to wrap every email address or phone number individually, which is easy to miss — especially in old posts, footer widgets, or page builder sections. Shield's auto-detection handles this automatically — set it once and contacts are protected everywhere.
The dual-layer security includes HTML entity encoding that works without JavaScript, but the click-to-reveal feature and full obfuscation require JavaScript to be enabled. Most modern users have JavaScript enabled. Pro includes advanced encryption that also requires JavaScript.
Yes. The plugin is designed to be GDPR-compliant. All security processing runs locally on your WordPress server. No external services are used for obfuscation. The free plugin has zero external dependencies — no CDN scripts, no API calls, no data transmission. Everything stays in your database. However, you should review your specific privacy requirements and ensure compliance with applicable regulations.
Yes. Shield works with Elementor, Divi, Beaver Builder, WPBakery, Gutenberg, Classic Editor, and any WordPress theme or page builder. Auto-detection finds email addresses, phone numbers, and physical addresses regardless of how your content was created.
