If there are other channels like that one I would not know or at least not remember. Every person I know, including me, would delete trash channels like that one as soon as it was found to be what it is.
While there are people that actually watch trash like that everyone I know is intelligent enough to not waste their time with junk. While we might install the channel to find out what it actually is it would get deleted as soon as its purpose was determined.
From time to time I run across channels like this that makes me feel that Roku was shortsighted in making their system so open but I guess the positives outweigh the negatives, mostly.
Two Roku Ultras, three Roku 3s and a Roku 1
