This isn't one comment to HN with 127 spelling mistakes, it would be equivalent to 1000s of people as part of a collective group contributing 1000s of spelling mistakes over the past 15 years, then all of a sudden fixing a ton of the mistakes.

Your argument is wrong but your point is correct. In the above scenario, should they be applauded for fixing 3 year old spelling mistakes that someone told them about 3 years ago...

Would someone criticize you for fixing them?

If you posted something the length of Moby Dick, with 127 spelling mistakes, which you then corrected?

No need to applaud, but no need to criticise...
