Earned 1114 credits in 4 days through supersonic ads, getting on average 30 videos a day to watch.
Also loads of useless apps to download for my ipad and iphone, utilised an old email account so no spam crap sent to me. Installed, payed out then promptly uninstalled.
one example, install Expedia...175 credits.
Trial play have been pretty good as well, but not one survey, i answer the qualifiying question and get told theres a problem.
Not complaining though.
