Rejection from that Stephanie Tignor sign up for new fitness program HIT:
Unfortunately it was brought to our attention that by asking for phone numbers, we unknowingly violated M-Turk's terms of service. I am so sorry about that - we were only using them for research purposes, and were just trying to make participation easier. Because of this, M-Turk is demanding that we reject all HITs. We've begged for another way, but they will not give us a better option. We are very sorry, truly wanted to run this program with you. It is out of our control. You will be bonused 25 cents.
That's some bullshit right there.
