Is it safe to remove Orkut?

view story

http://androidforums.com – On my zte merit z990g net10 it came stock with orkut in the /system/app and it runs when the phone boots and uses about 20k ram I can't kill it because it says it's a system process. I can freeze it with titanium backup but after freezing when I reboot its still in the running process list. So my question is how do i go about removing it and is it even safe to do so. I would just uninstall with titanium but since it runs at startup I'm afraid it might crash the phone. Does anyone know what I should do thanks! (General)
