At the present time, although the ad, consent form, and instructions tell the user that they have to provide their Fitbit data to participate in the experiment, many users will still accept and continue with the experiment, or will just auto-accept and leave the experiment open for the total duration. This ends up tying up the experiment links so that no one can accept them, and slows down the rate of data acquisition. Ideally, if possible there should be some way of creating an exclusion checkpoint earlier (possibly some Yes/No (e.g., do you own and wear a Fitbit tracker as a question prior to the consent form), or remove the ability to auto-accept, if possible, to improve the rate of data acquisition.
