In the “real world” the term may be better thought of as “cyber-stalking” or “creeping” but in the legal world it’s called Electronic Discovery (E-Discovery). Regardless of the label, your cyber-presence can be used against you in court. There are numerous examples of Facebook, text messages, e-mail, etc. being used as evidence of adultery, poor parenting, to refute an alibi, to demonstrate capacity to work, to prove substance abuse, and countless other things.
It would seem common sense that you shouldn’t change your status to “single” or “in an open relationship” if you’re married (and in South Carolina, you’re married until you’re officially divorced) but common sense seems to be hard to find in cyberspace.
