Not too surprised by ignoring the punctuation of numbers. After all, this year technically is the year 2,020. Much like we see numbers displayed in posts, often the commas are ignored.
We have computer shorthand these days.. e.g. .. you= u are= r, when we ask somebody how far the drove on vacation, they are likely to reply.. "I drove 3650 miles"..notice no comma. Just a sign of the times, I guess.
