GUBA are content thieves, that's a simple fact. In fact, they even go so far as to transcode videos to different formats, for example for easy viewing on the PSP (
source), etc. Clearly, that goes beyond simply providing Usenet access.
So what can we do? Simple, let's boycot them - and their affiliates.
2 easy steps:
#1 - don't use them yourself
#2 - send those trades, affiliates, etc. that you have that you know are using them a notice that GUBA steal content, and, possibly, that you may stop doing business with those using them
