The trick with Vagex is to select views to be as long as the time of your video.
If your video is 1:30 minute, then select "90 seconds - 3 credit x view" option
If your video is 2:30 minute, then select "150 seconds - 5 credit x view" option
Youtube view count is now smarter, so you need to make things more "legal".
Yesterday I upload into vagex a video with 139 views.
I use 300 views x 6 credits option (I spent 1,800 credits)
Today I checked my video and it had 408 views (no freezed view count).
Almost almost got my 300 views =)
This means that if you're goint to upload LONG videos to youtube, preper to spend a lot of credits
