In the end Google AdSense has resulted impossible to deal with. Their bots claim that I have copyright infractions in this blog but they don't provide any details whatsoever, making impossible for me to be able to correct such vices.
It was even suggested by some that the WP backup could be considered plausible copyright violation because there is another site with exactly the same content, go figure! Dealing with bots is worse than dealing with the worst bureaucracy apparently.
It has taught to me again this precious lesson: even if you wish to sell your soul, so to say, it's most uncertain that customers will be available.
Thanks for your support in any case.
