What can the police do about harassment? With adults on twitter and facebook?

[rayven]

Being that you can stop "following" people on Twitter, and you can "de-friend" someone on Facebook, the cops won't do anything at all since she can't be bothered to do the simple steps first.

Besides, harassment is a serious charge - petty arguments on social networking sites are usually ignored by police unless there is some sort of actual threat.

So the friend worried about the police can relax.

By the way, your question is extremely difficult to follow. Perhaps you should consider using punctuation and full English sentences.
