I have heard my girlfriends complain that their boyfriends changed their status without telling them, or some pervert showed his privates on her wall. Others posted offensive comments on their walls, inciting a verbal riot; and still others put links to porn or even illegal activity on their walls. Then there are the mellow account holders who display their family photos, recent trips to Disneyland, and their grandmother’s 80th birthday celebration. Still yet, depending on how many groups you belong to or friends you have, the barrage of messages, alerts, event invitations . . . is overwhelming. And the final straw is when you just sign on for a moment to check your messages, someone tries to chat with you. Usually some guy who thinks you’re cute and is scamming for chicks.
