GetTor needs official two-factor-enabled dropbox and google accounts
We're already using dropbox links in gettor reply message. This dropbox account was not created using a secure email address and is for test purpose only.
This is very important as an attacker may find a way to reset the password of that dropbox account and replace legit bundles with malicious ones.
