very nice topic!But how one puts a signature in his profile,I cannot put links 
you need to boost your activity for that
you need to be atlest a jr member to post a link in your signature as a newbie you can not have any link in your signature it take 30 days of activity to become jr member
Then you can just buy an account.
Many buy accounts and I am sure some people are professional posters and have many accounts. If you live in a poor country, you can make the average salary by posting on bitcointalk
