Monetisation sucks.

Firstly adsense - If you take out the gold sellers and the character selling adverts your not going to be left with much. I've not done much adsense for a while now but it's filtering options used to suck. Also you are selling your traffic cheap, You would be better off signing up for the affiliate programs of the gold guides, and levelling guides and putting those up instead. However with wotlk round the corner would anyone be buying a how to make gold guide right now.

Have you considered pay per view or pay for access to multiboxing videos of multiboxed arena and such. obviously you can't host them on this site, that would just blow the bandwidth budget, but if there was a site that allows you to control access to your videos then you could potentially sell access to those. It needn't sell for much. Put cut down teasers on this site, on youtube etc and charge a couple of bucks for access to full videos.

Just a thought.

I know I love watching multiboxing in action.

Here's another thought. Arrange some deal where you pay for the rights to show other members videos and you will have content galore.
