You can detect nasty ad blockers. Online example: http://sitexw.fr/fuckadblock/
(There is also a project, BlockAdBlock, with a more convenient name)
Come and see the future of FuckAdBlock: V4 Beta

// The number of milliseconds between each check

// Displays the debug in the console (available only from version 3.2 and more)
debug: false
// Allows to set options
// #options: string|object
// #value: string
fuckAdBlock.setOption(options, value);
// Manually check if AdBlock is enabled.
// Returns `true` upon completion of check.
// Returns `false` if check cannot be performed (eg due to another check in progress).
// The parameter 'loop' allows checking without loop several times according to the value of 'loopMaxNumber'
// Example: loop=true => time~=200ms (time varies depending on the configuration)
// loop=false => time~=1ms
// #loop: boolean (default: true)
fuckAdBlock.check(loop);
// Allows to manually simulate the presence of AdBlock or not
// #detected: boolean (AdBlock is detected ?)
fuckAdBlock.emitEvent(detected);
// Allows to clear all events added via methods 'on', 'onDetected' and 'onNotDetected'
fuckAdBlock.clearEvent();
// Allows to add an event if AdBlock is detected
// #detected: boolean (true: detected, false: not detected)
// #fn: function
fuckAdBlock.on(detected, fn);
// Similar to fuckAdBlock.on(true|false, fn)
fuckAdBlock.onDetected(fn);
fuckAdBlock.onNotDetected(fn);
(Available only from version 3.1 and more) By default, FuckAdBlock is instantiated automatically. To block this automatic instantiation, simply create a variable "fuckAdBlock" with a value (null, false, ...) before importing the script.
<script>var fuckAdBlock = false;</script>
<script src="https://github.com/sitexw/FuckAdBlock/raw/master/fuckadblock.js"></script>
After that, you are free to create your own instances:
fuckAdBlock = new FuckAdBlock;
// and|or
myFuckAdBlock = new FuckAdBlock({
checkOnLoad: true,
resetOnEnd: true
});
