It turns out that sabotaging another person's Facebook page could be a criminal offense. An Irish man did avoid jail time for posting an offensive update to an ex-girlfriend's page, but he still has to pay a hefty fine.
The man thought his girlfriend was cheating on him, so he went to her home to confront her. He then left her house and took her phone with him. He used it to log in to her Facebook page and post a demeaning status in her name.
You should always be careful what you post on social media, and never illegally access another person's account.
Just because something hasn't been prosecuted before, doesn't mean it isn't a crime. In the technology age, it is always better to error on the side of caution and use common sense. Even the judge was taken off guard.
The judge noted there was no relevant precedence to guide him in sentencing. He called it a reprehensible offence which seriously damaged the woman’s good name but said that “fortunately” the status was quickly spotted and taken down.
