Table Tennis Database

Sunday, December 8th, 2013

UPDATE: Changes #1 and #2 have been rolled back. After hearing reasonable feedback from concerned members of the community, the choice was clear that this wasn’t the best method.

The mission of the Table Tennis Database is to provide a platform for giving ratings and reviews that are:

  • Accurate
  • Useful for people’s research
  • There are several reasons why reviews and ratings aren’t always accurate (whether accidentally or deliberately), and we’re taking steps to uphold this mission and maintain quality as much as possible. Some of the changes that we’ve made include:

  • Users cannot give an Overall score below 5. Does anything really deserve lower than a 5/10? Let’s be reasonable; every item is useful to a particular type of player, even if it doesn’t suit your needs. Very low scores unfairly affect the average numbers drastically.
  • Past Overall ratings below 5 have been changed to unrated (as if “overall” was left blank).
  • We had debated changing those low ratings to 5 (the lowest allowable rating), but decided against the idea of changing a user’s ratings without permission. If your rating was affected, you can always login and update the rating.
  • All users with affected ratings have been notified by e-mail and can update the blank “overall” ratings with a more fair score.
  • Users cannot give a Speed score below 4 for a rubber or blade. Only a freshly cooked pancake could produce speed scores lower than 4, otherwise it’s not physically possible to be that slow.
  • Users cannot give a Control score below 3.
  • Already many user accounts have been shut down as suspicious ratings and reviews were detected, and hundreds of ratings have been deleted. A sophisticated algorithm is in place to detect malicious ratings and they get deleted one-by-one. There is also a sophisticated keyword detector for preventing spam.
  • In order for the Table Tennis Database to continue to be a great resource, we will continue our commitment to protecting rating quality.

    Do you have more suggestions for maintaining the quality of the ratings and reviews?
