I don't think buying untargeted (popunder) traffic for a tube is a very good idea though. Tube sites have the lowest revenue-per-user of pretty much anything so it would be next to impossible to buy traffic profitably.

Tube sites should SELL untargeted traffic, not buy it.

If you have a self-hosted tube you should try to buy traffic from aggregator sites. Adultwebmasternet is a good place to start. This traffic will be targeted (they specifically want to watch your video) so it can be profitable.
