Recently i have created some of profile in forums. While creating account we have to give captcha for human verification. Nowadays robots or software are so smart. People are using the software for mass profile account creation. So that some of site owner would like to verify many time to avoid the spammer.
Here is the one i took. He is restricted the robot by verifying five times. :)
And finally i have met a brilliant spam question. Take a look at this. Take a brief laugh
Conclusion: Avoid using software to create profile. make site owner happily forever.
