I'm planning to misreport all my clients behavior.
That doesn't sound right. Why wouldn't you correctly report on their behavior?
I'm doing it after I read some blogs about the right to privacy on the net. And how this could help.
If you're responsible for monitoring your client's behavior, then you need to accurately report what they're doing. If you misreport their behavior, then they may not get the help that they need and you may get in trouble with your job.
I just want to help them by misreporting their behavior.
I don't see how this would help them. Even if it does, it's still wrong to misreport because that isn't your job. You could be fired.
