If someone is harassing you and saying things about you and this has been going on for almost a year and I haven't been around them but they harassed me on facebook what can be done

Talk to a officer and file a report. It will be up to them to help you. I'm not a officer, but that is your first step.

Delete fakebook

Its online harrassment which means there is nothing that can be done because the supreme court decided online harrassment isnt the same as in person harrassment so there r nearly zero repercussions for it. I'm sorry.
