I imagine that an army of twitter bots sending automatically thanksgiving messages could mess with the results. A sad event in christmas would be balanced by the global cheering and be perceived as "less sad" by the program than in a common day.
The opposite is also possible. That bots can be programmed to create outrage deliberately is not a secret. Outrage means bussiness for newspapers so is a desired goal.
