Please see this question: What's wrong in this iban validation code?
I think this kind of thing will start to hurt Stack Overflow.
Because the original question contained a spammy link and the User's rep is essentially 0, I'm guessing either the question is not real and is just a vessel for the spam link, and the OP has no intentions of coming back to provide more information for answering this.
Over time, will Stack Overflow be cluttered with a bunch of dead-end questions? What happens to these?
