In the past I have been told that you can use tools like Tube Mogul to auto submit a single piece of video content to lots of different video sites and that it is not considered spam.
After watching Rand's Whiteboard Friday I am more skeptical of this tactic.
Here are my list of reasons why doing this would and wouldn't be considered spam.
This is not spam because:
These video sites are individual sites with an individual user base.
This is spam because:
Google does not want duplicate content of any kind in the SERPs.
I leaning towards spam but have seen this be very effective in the local space.
So I'm torn.
