Youtube sandbox????

O.K so I payed good money for a awesome vid for a niche i'm banking on ..I put the vid on youtube and in 3 days I had reached almost the top of page 1 for my keyword. Then BAM my vid is gone..not gone completely.I can still find the vid using other keywords that I put it under but not the main keyword I needed it in...WTF does youtube sandbox ???

Yep, the only time I ever seen it happen is with fake views, or if the video is new it could go to the top and slowly drop.

The views are real. I have it linked to a goarticle that I have ranked #1 on google for the niche. Most the traffic is coming from the goarticle.
