Would you report to G if you found out your competitor is cheating to gain better Search Engine ranking; using paid click fraud for adword or adsense etc?
No personaly i wouldnt its not nice to tattle tale.. But now say if they copied my content or stole my ideas then now it might be diferent then it would be personal.. lol
I am sure you were a big fan of Pollyanna while you were a child Google can not even find one of my competitors hidden texts on his 10+ domains. For the topic If the trick is an easy one (hidden text etc) I report it but if it is a good one I don't report it.
actually, i jsut googled "internet serious business" and picked an image. no clue who that guy is maybe not, but if google finds out he gets high clicks with little conversion, he'll be banned
Google manages to see always if content was copied, or if someone is trying to use paid click fraud it's just a matter of time until cheaters are discovered.
