The best way is using a Flash Cookie as most dont even know they exist. I catch alot of Chinese hackers with a signup flash cookie that is embedded into my FlashCaptcha. On every signup we check for the cookie and compare flash Language against the Browser & System langs. I love when I see Flash Lang=CN,System=en,Browser=en = Signup No worky!!
We also capture the IP they use to signup so we can always ban specific IPs if needed Eric On Fri, Dec 26, 2008 at 11:09 AM, Phillip M.
