The folks at e-rewards and whatever company(s) own them, are not out to help the world by collecting "good useful feedback", they are in business to make money (nothing wrong with that, per se), and are "using" us (with our permission) by throwing us some breadcrumbs which we've each decided for ourselves, is sufficiently worth our time (not to say we don't grumble about it on occasion), which said crumbs sometimes we receive...and sometimes we don't, sometimes we "fight" for them, and sometimes we just let it go as it's not worth our add'l time... it's really great that you want to help businesses get "good useful feedback" (and that's not sarcasm), but I think most would agree there are better outlets worthy of your energies to help out in this world than e-rewards, if you have the time and the inclination to do so... speaking only for myself, it fills a few idle moments of my life, for which I get some airline miles, in return for which I'm happy to honestly respond to their surveys, but have no illusion as to their "mission" 😵‍💫
