Complete pirates. Totally unethical.After sending out your free survey, carefully navigating away from the paid for features (which it "helpfully" flags for you), you send your survey out... and only then, after asking friends/colleagues to fill it in, you find you can only view 10 responses, unless you pay them £99.They prey on people by wasting their time, and their friends' time, by asking for an exorbitant fee to unlock the results. Shameful behaviour.
