There was a moment in time at 8kun's beginnings when Tor posts could post with a shared unique alpha-numeric user ID other than 0000000
But not everyone saw the alpha-numeric ID.
For example, multiple people would post on tor and all share the same unique alpha-numeric user ID that was visible to some anons, but other anons would see it with 000000.
It was all funky back then.
Take a look at that date of the post and you will most likely see that Q did not post 16 times in that bread as your image shows 16 posts by that ID.
I believe that is what is happening with the discrepancy
FUCK, I've been here forever, and remember too much.
