If you send her dick pics, dead animals pics or photos of apes with "this is how you look like" under it, all that from hundreds of different accounts so that she can not effectively filter it, then yeah, you are trolling and harassing.

Likewise, if you flood someone employer customers with the above material to get him or her fired, you are harassing.

Let's not pretend this was just about "slightly impolite words". Or misunderstood dialog.
