This is because you are asking for usernames in one of your forms, this is the form ID where you have these fields #61275175783160.
I had to remove those fields in order to activate your account, but please take a look to our terms, there is stated that you cannot ask for usernames, passwords or CC info, this is why a form can be disabled and an account suspended: http://www.jotform.com/terms/.
Please avoid to use words like username or password as well, even if you're not asking for this info in a field, but you have this text in your form it will be disabled, this will help you to avoid your forms be disabled again.
