The survey found 58% of respondents had looked up two or more past partners, and 15% had actively changed their Facebook status expressly to make a current or past partner jealous. Almost half admitted to reading their partner's emails to look for evidence of cheating. Men were more likely to stalk women, with a tendency to spend 8 minutes or more "spying" on their partner's profile per day.
This jives well with previous evidence about Facebook increasing jealousy in relationships. The kind of jealousy that can ruin them. But with the survey also revealing that 20% had scratched up an ex's car with a key and 39% took revenge on an old flame by spreading false rumours, we can't help but wonder if the survey participants were chosen from the pool of past Jerry Springer panelists.
