## What it is
A small JavaScript library that detects whether visitors are using ad blockers like AdBlock. It works by placing bait elements and checking whether they are hidden or blocked, then triggering callbacks.

## Use cases
- detect if a visitor has an ad blocker enabled
- show a message asking users to disable their ad blocker
- conditionally hide or show content based on ad blocker presence
- track how many site visitors block ads
- prevent site features from loading when ads are blocked

## When to choose
- you need a lightweight, dependency-free ad blocker detection script
- you want broad browser support including older browsers like IE8+
- you want a simple callback-based API with configurable bait elements

## When to avoid
- you need guaranteed detection against modern, sophisticated ad blockers
- you want to block or punish users rather than just detect
- your project requires actively maintained software with frequent updates
