And WTH is the point of all this Korean spam? Don't they know that nobody will bother to read it? ; D
It's posted by bots. They search the net for any site they can hack into with a brute force attack. That's why there's captcha. If the captcha doesn't lock out an ip address after 5 failed attempts, they'll get in. Even that's not guaranteed to work if the hack is by thousands of botnet zombies operating out of places like Alice's Beauty Parlor where the computer's antivirus is five year's old if they have one at all.
I don't have to be able to read Korean to know that the spams about male performance chemicals or porn. We are a sorry excuse for a species.
