At least on two sites: SO on Russian and Русский язык SE Data Explorer returns a lot of comments with negative score [-6...-1]:


Actual comments look like normal comment without upvotes.

What is this? An echo of migration from hashcode.ru?

    What happens if you upvote one of those comments? – Sonic the K-Day Hedgehog Nov 23 '18 at 9:38
  • @SonictheInclusiveHedgehog nothing special, it gots upvote. But due to the delay of SEDE data update you won't know right now. – αλεχολυτ Nov 23 '18 at 9:43
  • A score of 1 you mean? – Sonic the K-Day Hedgehog Nov 23 '18 at 9:48
  • @SonictheInclusiveHedgehog for all other comments N score mean N upvotes. – αλεχολυτ Nov 23 '18 at 9:51

    maybe they were answers and a mod pressed the magic 'convert to comment' button? – AakashM Nov 23 '18 at 13:47
  • @AakashM, yep, seems so, for example for this comment. It was answer with -10 before – Grundy Nov 23 '18 at 13:53

    @AakashM not sure, cause big SO doesn't have any one. Do you believe that 'convert to comment' was never pressed on SO? Even more in such case there were deleted answers on questions, but they don't exists. – αλεχολυτ Nov 23 '18 at 13:56

    Migration from the original site appears to make more sense: they copied the score to database as-is, and they do have sanity check when displaying preventing negative score from being displayed. – Shadow 10 Years Wizard Nov 26 '18 at 15:16

    @ShadowWizard comments v 2.0. – αλεχολυτ Nov 26 '18 at 15:25

    @älёxölüt why can't I downvote your comment? Do I need more rep for this? – MEE Nov 26 '18 at 16:16

Upon investigating this issue further it does seem that these are leftovers from the migration.

The most recent voting history we have in our databases (that I could find) is for April 2015 (Technically, March 31st, but oh well). This means that we do not have the actual votes for these comments and thus I can't say where they came from with certainty.

The migration theory is supported by the fact that the most recent comment with a negative score is from March 12th 2015, if it was from answers being turned into comments there would be more recent ones.
