If there is sudden splurge in the traffic, which is mainly from the Orkut, does it come under the scanner of Google? Since, i have come across many softwares that ma help you increase the visitors to your site. How ethical is the use of such things?
No if your traffic is genuine then you needn't worry anyway the traffic from orkut is not targeted as they must be your friends or people who want to simply pass their time so you aren't going to make much out of them so dont worry. But this is only if you are not spamming, orkut is also owned by google and you can never trust them who knows they might be tracking all that too...
