Most of good ad network will not accept a free domain.. a .xyz domain will cost 2$ / year, you should invest ^^
AdSense is quite rigorous (adult sites better start looking for alternatives ) and even if you're accepted at first, you can get on a blacklist soon after. So even if you go for AdSense, this shouldn't be your only profit source. It's best to have a back-up just in case.
Try exoclick, i have good rates with them. 0.05 for a simple banner, 0.10 for small instant message. or try a popunder network -> popads is the best i have found. At least 1.5$ CPM.
In shorte.st you get $1.42 / CPM for views from the Czech Republic.
do they do classic cpm banners? or only popup via "website script"?
Popads only has pop-unders. I can recommend them as an AdSense alternative..
