First you increased sb's page-rank (spending time on a website = selling your time) and sold your valid e-mail address.
Then sb earned some $ on ads and you sold your time and a valid e-mail address again for a lottery (the organizes always win).
And then you provided sb a hell lot of data (google "data mining"), your, guess, valid e-mail and a lot of time you could have spent doing something more profitable.
Later on you froze your BTC's and then sold some of your time again.
Now do the maths: the amount of BTCs you made divided by the amount of time you sold. I don't know how much an e-mail address is worth, but let's assume you've made 5 BTC in 12 hours. That's 0,41(6) per hour. Minimal salary in my country equals 0,46875 BTC per hour.
It's pretty good if you want your first BTCs and to see how it works, but not so good in the long run... ;-)
your country puts the minimum salary in BTC???
