I am so sorry to hear this. I'm also totally shocked. Out of all the survey sites I belong to, Prolific is the only one who hasn't screwed me over. I think it's terrible what these survey sites do as far as banning people with absolutely no explanation. It's all a big secret and cover up. That shouldn't even be legal, but obviously it is very much legal for these survey sites to drag their survey takers through the crud and treat them horribly.
