Banned by law - yes - just like crypto is still illegal in some jurisdictions. Banned by technical means: this will be very hard. A 3node receives and send encrypted traffic only which is hard to recognise as “specific traffic” for this project. There is such an amount of encypted traffic all over the place that identifying and blocking it is a very labor intensive task.
As @Geert said, also we use an overlay network that has it’s own point to point routing protocols so the TF GRid is less relying on central exchange on connection points. End points are able to find their own “route” to the destination node independent of network routing (very cool!).
