Buying Safe YouTube Traffic

I just had a video removed from YouTube for "Violation of TOU #4 Section H". Until now I have had great success and few problems with YouTube marketing. Views are important, and I need to figure out what our safe options are.

These are the sources I used for my video:
Vagex: Seemed like I had low views results compared to what I ordered. I ended up with a few hundred views here and a handful of likes.
YTNuke: I ordered 2,000 views
u2bviews: I think I got a few hundred views here as well as likes and subscriptions.

I was thinking these were all part of view exchanges which should be safe. It seems that from the email YouTube sent it is allowable to purchase traffic as long is it isn't from robots/spiders. Here is part of the email:

"Many users trust outside marketers who claim to increase views, subscribers, likes, etc., but each user is ultimately responsible for the activity on his or her account, as well as for knowing and abiding by YouTube's Terms of Use. This includes understanding the nature of the traffic on his or her channel and making sure any hired service providers comply with YouTube's Terms of Use. "

This tells me it is OK to hire providers, but they have to comply with TOS.

With all that said, does anyone have any ideas on where it is safe to get views?
