i'm not really thrilled with installing that app to find out how to block it (it installs a .mobileconfig file to get the application).
You might want to see if you can blacklist that site at a network level (firewall, proxy, whatever)...
if you can't get it blacklisted at the network level, you can always change the DNS for tweakboxapp.com vi either /etc/hosts or a dns resolver file so that it points to 127.0.0.1 (or if you are mean, something like sadtrombone.com)
or
push out a config profile with casper that sets that URL to be denied via parental controls

If you block the ability for students to install configuration profiles this app is unusable.
