I am working on a few proxies right now and I am intending to buy a domain name something like "Unblockorkut" or something like that. I was wondering, if there is any chances that I would get into trouble? I know that if you have the word "google" in your domain, they may sue you or something. I don't know if that's true. Thank you for your time.
Don't use a famous mark in your domain name when your site is about their product or services - it's going to be trademark infringement in the way you are suggesting. Yes, you can be sued. Your domain could also be taken in a UDRP action.
