Heck no!
Here's why:
Parents should know who their children's friends and acquaintances are and know what is occurring in their children's lives. If that means snooping, so be it. Period
If you suspect that something serious may be happening then, it’s ok to snoop. Parents honestly don't enjoy snooping, they don't get a kick out of it, but do it to protect their kids.
Parents should guide their children to be responsible, well-rounded individuals and prevent their kids from being drug addicts, victimized by predators, and from doing anything that might get them charged or thrown in jail. It's a tough balance. Add to that the everyday activities of earning money, getting everything you can for your family, etc.
As children hit their teens, more independence and exploration will be required. This still needs guidance.
Here is the advice: a way a kid can gain more privacy is actually by being open about their IM friends, etc. If they actually tell their parents what they are up to, their parents will certainly be really embarrassed about their snooping since the kid will say: "I TOLD YOU what I was doing and with whom, and you were fine with it!!!! Either you don't trust me when I tell the truth, or you don't listen to me when I tell you about my life". So you have to really show leadership in your life by being open, trusting, and transparent with your parents, and then they can back off.
Of course, if the child is very mature or of age, the child can probably move out, get a job, and pay for their own internet, cell phone, apartment, electricity, car, food, schooling, computer, and clothing. Until then, it's their parent's house, mortgage, fridge, stove,etc.
