Irrlicht3d.org - How I got banned from Google Adsense for life time
Apparently this is happening more frequently these days. So if Google are starting to screw people over how can we trust anyone anymore? It's not so much that they did it, but more that they provided no justification nor gave a chance of appeal. Sounds a lot like PayPal really, and if Google go that way I may lose a serious amount of respect for them.
Do no evil... unless it's convenient and saves you some money.
