Disable duplicate responses by default
By default, any participant can send the same answer several times. The total count then makes no sense.
For example, to the question "What do you at night?"
one can answer several times "I play guitar."
While in most cases we need them to send each answer only once.
We need the default behaviour to allow any answer to be sent only once per participant.
We’ve disabled duplicate responses on multiple choice activities by default. Thanks for your suggestion!
