You could be sued at any time for most any reason, so really the issue is whether it's likely to happen. Both "Gugle" and "Feysbook" look different enough to me. Usually when a powerful company goes after someone for cybersquatting it's because the person has used the original trademarked name and changed it in a minor way such as altering one letter or changing the ending from .com to .co or .net. Google and Facebook would need to show that you registered the domain with the intent to profit off their trademarked name. Instead of suing, I think they'd be more likely to contact the hosting company and send you a cease and desist letter, if they do anything at all. Of course, I'm not an attorney and it may be worth it to contact a professional.
