Edmodo was a popular site for K12 education that shut down about a year ago. At the time, I thought that the closing was a function of financial problems brought on by their free tier. This position was seemingly promoted by Edmodo.
“After more than a decade of ensuring Edmodo can stay a free tool for all, we have found that it is no longer viable for us to maintain the level of service you deserve and that we can take pride in ourselves,” the company wrote on its website. “As a result, we have made the difficult decision to shut down Edmodo.com.”
It may have been more than that. About a month ago, the FTC announced that it was suing Edmodo for collecting student personal information in a way not allowed by COPPA. Schools can vouch for students when student information is only used for educational purposes. It turns out that the information collected from students was used to target ads.
