Given the fact that Adsense does not allow you to sign up for an account using a subdomain of tumblr, I would imagine that even if you sign up with a different domain and then create and put Adsense on your Tumblr page, you will be penalised. So my question is, what's the best alternative of Adsense which allows adding ads on free-hosting websites?

"The Tumblr Terms of Service require that your blog be used primarily for blogging, but they do allow you to use AdSense or other ad systems as long as that’s not the primary focus of your site." - http://www.howtogeek.com/howto/22559/how-to-add-google-adsen...
