## Description

Your contact form is filling up with junk: throwaway addresses, gibberish names,
bot submissions, and — increasingly — enquiries written by AI that read exactly 
like a real person. Your sales time goes on chasing ghosts, and if you run Google
or Meta ads, every junk conversion teaches the algorithm to find you more of the
same.

LeadShield screens every submission in real time and blocks the fakes before they
land.

**No CAPTCHA.** Real visitors never see a puzzle, never tick a box, never identify
a fire hydrant. Detection is invisible and runs on the submission itself.

#### What it checks

 * **Email** — syntax, live mail-server (MX) lookup, a disposable/throwaway domain
   blocklist refreshed weekly, and typo rescue (someone typing `gmial.com` is offered`
   gmail.com` instead of being lost)
 * **Behaviour** — a hidden honeypot field, how fast the form was completed, and
   whether a human actually typed, moved a mouse or touched the screen (mobile taps
   and browser autofill are recognised as human, never penalised)
 * **IP reputation** — known abusive addresses, via live threat data
 * **Phone** — format and region validity when a phone field is present
 * **Device fingerprinting** _(Pro and Agency — included in your first 14 days)_—
   catches the same device submitting over and over. Hashed in the visitor’s browser;
   no third-party tracking scripts are loaded on your site
 * **AI content analysis** _(Pro and Agency — included in your first 14 days)_ —
   reads the whole enquiry in context to spot machine-generated spam text and fabricated
   identities

Every submission gets a 0–100 risk score and a plain-English reason, so you always
know _why_ something was blocked.

#### Fail-open by design

If LeadShield is ever slow or unreachable, your forms submit normally. An outage
on our side can never cost you a real lead. This is a deliberate design choice: 
we would rather let one junk lead through than lose you a customer.

#### Works with your existing forms

One setting, no per-form configuration. Automatically protects:

 * Contact Form 7
 * WPForms
 * Gravity Forms
 * Elementor Forms
 * Ninja Forms
 * Formidable Forms
 * WooCommerce registration and contact forms
 * Any other form on the page, including ones added dynamically by page builders

#### Pricing

 * **Free** — 100 validations/month, free forever, no credit card
 * **Pro** $99/mo — 10,000/month, plus AI analysis, device fingerprinting, webhooks,
   CSV export and Google Ads / Meta exclusion exports
 * **Agency** $249/mo — unlimited, one account for all your clients’ sites, plus
   tunable risk thresholds and configurable data retention

Every account starts with 14 days of Pro — no card — and then stays on the Free 
plan unless you upgrade.

#### Privacy

The plugin sets no cookies and no browser storage on your visitors, and loads no
third-party tracking. Screened lead data is deleted automatically after 90 days 
by default (configurable, down to zero, on the Agency plan). Exactly what is sent,
and when, is listed under External services below.

### External services

This plugin connects your forms to the LeadShield.ai service, which screens each
submission for fake, bot and spam leads. It does nothing until you save a LeadShield
API key in Settings  LeadShield.

Once a key is saved:

 * Front-end pages load the LeadShield script from https://leadshield.ai/js/shield.
   js. As with any externally hosted script, the visitor’s browser connects to leadshield.
   ai to fetch it, so the service receives the visitor’s IP address and browser 
   user agent.
 * When a visitor submits a protected form, the script sends the form’s email, name,
   company, phone and message fields, the page address, how long the form took to
   fill in, whether keys, mouse or touch were used, a one-way device hash and any
   ad-click IDs in the page address (such as gclid or fbclid) to https://leadshield.
   ai/api/validate, which replies with a verdict. The visitor’s IP address and user
   agent are part of that request.
 * Nothing is sent from a form until it is submitted.

The service is provided by LeadShield.ai: [terms of service](https://leadshield.ai/terms),
[privacy policy](https://leadshield.ai/privacy).

## Installation

 1. Install and activate the plugin.
 2. Create a free account at [leadshield.ai/signup](https://leadshield.ai/signup) —
    no credit card required.
 3. Copy your API key from your LeadShield dashboard (the “API key” card).
 4. In WordPress, go to **Settings  LeadShield**, paste the key, and save.
 5. Test it: submit one of your own forms using `test@mailinator.com`. It should be
    blocked, and appear in your dashboard within seconds with the reason shown.

## FAQ

### Will it block real customers?

Hard blocks are reserved for high-confidence junk (score 70+). Borderline submissions
are marked “suspicious”, and you choose whether those are blocked — there is a setting
for exactly that. Every verdict carries a plain-English reason you can audit in 
your dashboard, so nothing is a black box.

### Do my visitors have to solve a CAPTCHA?

No. Detection happens on the submission itself. Genuine visitors notice nothing 
at all.

### Does it slow down my site?

The script is small and loads asynchronously, so it never blocks page rendering.
Validation typically completes in well under a second, and there is a hard 5-second
timeout after which the form simply submits.

### Does it work with my form plugin?

Almost certainly. It attaches to every form on the page rather than integrating 
with one specific plugin, and it watches for forms added later by page builders 
and single-page themes.

### Can I protect only some forms?

Yes — enter a CSS selector in the settings. This is useful on WooCommerce, where
you may want to protect registration and contact forms but leave checkout completely
untouched.

### Is there really a free plan?

Yes. Every account starts with 14 days of Pro, then stays on the Free plan — 100
validations a month, for as long as you want it, no card. There is also a free no-
signup audit at [leadshield.ai/audit](https://leadshield.ai/audit) where you can
upload a CSV of leads you already have and see how many are junk before installing
anything.

### Does it show a “Protected by LeadShield” badge on my site?

Only if you switch it on in Settings  LeadShield. It is off by default.

### What happens if I hit my monthly limit?

Submissions pass through unvalidated until the limit resets on the 1st — your forms
keep working normally. You are emailed at 80% and 100% so it never happens as a 
surprise.
