This is a strange one: there is a deactivation link, however after trying we could still log in. Above all, this page http://mymfb.com/gettingstarted/article/article_42 states it’s also possible to reactivate your account. Hence: beware before even creating an account here. Otherwise try contacting them using: http://mymfb.com/contact/
