I don't have my notes on it, but I believe you can try to set a cookie and then try to read that cookie. If the cookie isn't there to be read you know that surfer isn't accepting cookies.

Of course that won't tell you know many are using some form of private browsing or an add-on of some kind which will flush all those dirty porn cookies as soon as someone quits their browser session. All of those things can contribute to lower signups being credited to affiliates.

Too many porn surfers are being educated to believe cookies are a bad thing (which I'm not sure all sponsors mind). Might be worth thinking about ways to convince surfers why some cookies are valuable/helpful *for them* so they won't be as likely to go cookie-free about the Net.
