Or.. be very worried since this is one idiot on twitter and there are thousands of scientists who are now looking into this and are finding we are being poisoned on a daily basis and these companies knew it/know it and continue to do nothing.
Some feedback.. your front page doesn't mention subscriptions or service prices but your T&C's does. It seems a bit disingenuous to give all the user info and email prior to disclosing the costs. If you are giving the service away for free right now, you should be clear about that on the page.. so it's free now and at some point you will turn someone's form off unless they start paying or is it free forever for the folks who are using it during this 'free' period?
