Leroy Jenkins is more important than your marriage

Social sites and massively multiplayer online games aren’t just a great place to catch up with friends and be entertained, they’re also a great place to dig up dirt on a soon-to-be ex. Which, let’s face it, is one of the lamer reasons for why you’re being divorced.

The American Academy of Matrimonial Lawyers says 81 percent of its members have used or faced evidence from Facebook, MySpace, Twitter and other social networking sites, including YouTube and LinkedIn, over the last five years.

Evidence like:

Father seeks custody of the kids, claiming (among other things) that his ex-wife never attends the events of their young ones. Subpoenaed evidence from the gaming site World of Warcraft tracks her there with her boyfriend at the precise time she was supposed to be out with the children. Mom loves Facebook’s Farmville, too, at all the wrong times.

So the next time you’re clanning for a new scepter of intelligence +25 in World of Warcraft, or logging 10 hours in Farmville, you might want to remember that someone could be watching … and taking a few notes.
