I think hamsters have too many participants and a lot of rules to make, but the results are not comparable to all that is seen from a lot of participants, compared inversely to dogs, doing a job that is not too difficult and not too many rules to be done. So a lot of participants just benefit the developer to make a lot of rules and receive rewards from what is specified and not returned to the participants.
If you compare, in my opinion, as a participant too,, you can be sure dogs are still much better than hamsters.
