He is rude, bastard, mean, scammer. Owner of 123ORKUT.COM The name containts the word 'Orkut' . How to get him ****** ?
I can't vouch for them but there are some websites were crackers claim they will get you email passwords or mess up a website for $150 to $250. I'd heard they are often scams so that's risky too. Whois says the site operates... in India. I doubt there is much you can do here.
email orkut support and let them know someone might be infringing on their intellectual property rights... Though that could end up in a settlement so he might actually net a profit of that. BTW: his domain name is not privatized: http://www.yougetsignal.com/tools/whois-lookup/ That will give you all of his info.
