Nah, that has been posted a ton of times in different threads. Nobody is bothered by that.
I use unblock.us and it's pretty great. I keep it active on my Vita and PS3 and leave it off my 3DS and Wii U so I can watch American Netflix on my Sony stuff and Canadian Netflix on my Nintendo stuff in the rare case that something is only available in Canada. Totally worth the $5 per month.
I don't think Netflix particularly cares, either. I think they're willing to turn a blind eye to stuff that makes Canadians more likely to subscribe to Netflix.
Because if I couldn't use it any more, I'd very likely cancel Netflix. I ran out of stuff to watch on the Canadian side ages ago.
It's still cheaper to use those points cards to buy VC games in Wii mode and pay the upgrade fee than to just buy the games on Wii U.
