Both are possible, and both are illegal in some places, so I won't encourage them.

I think the internet is one way you might collect information about people, like their email addresses, or what they’re saying in social media.  But I don’t know what you mean by “intimidating” an individual. Can you give me some more context here?

It depends on what you mean by cyber stalking. Do you mean the practice of using the internet to collect information about an individual? Or do you mean the practice of intimidating someone using the internet?
assistant
