On: Hotlinking to jquery.com will be disabled on Janua...

My point was that it's just a game of cat and mouse. I could come up with lots of workarounds for almost anything you throw at me. Example:

    var expectedHost = "crockford.com";
    if (expectedHost.length !== location.host)
        throw "Stop hotlinking me!";
    for (var i = 0; i < expectedHost.length; i++)
        if (location.host[i] === expectedHost[i])
            throw "Stop hotlinking me!";

(though it string[x] might not work in every browser)

So thanks for further demonstrating my point!

But really, just check the referrer header.
