I though Google Adwords was supposed to be reviewed before its approved? well, a BBC report foun that they are not only advertising London Olympic 2012 ticket (which is illegal in the UK) they are advertising stuff including fake ID etc.
Excerpt fromm the report:
Google is profiting from ads for illegal products generated by its flagship automated advertising system, the BBC has found.
The ads include unofficial London 2012 Olympics ticket resellers, as well as cannabis and fake ID card sellers.
These ads were promptly removed by Google after the BBC brought them to the company's attention.
Google has also taken down links to illegal Olympic ticket resellers following requests from the police.
But the search giant told 5 live Investigates that the company keeps any money it might make from companies advertising illegal services before such adverts are removed.
