ultrasurf use port 80 or any other open port

therefore difficult to prevent

don't have any filter tipping point device and you can't prevent any firewall.

There are a lot of blocking method on the forum web site

but it does not work

You might have a chance with the AppDV Subscription to block this kind of traffic.
