I pulled out of Ecademy.com a long time ago, sick of the unsolicited pestering that came with membership of the business networking site. The Register reports that it recently became the target of a Nigerian '419' bank fraud scam. So no surprises there.
In the article, Julian Bond, Ecademy's CTO, agrees. "Social networks are another form of communication that is being attacked. Just like email," he wrote in an IM to The Register. He readily admits there's nothing stopping someone from gracing an account with the name and likeness of this reporter or anyone else. And he says Nigerian scams like the one Jongsma received are reported as many as 10 times per month."
