I notice these days they no longer give any credit on disqualifications despite you were disqualified after more than 95% completion and already spent 19 to 15 min on the surveys. I have encountered 2 such faikures. Very dismayed.
In the past they often gave at least a partial credits. I haven’t done survey since late March till early June due to out of the country. No idea when this crappy cheating pattern started.
