Oh all of my configs are deny root ssh login or without-password. I noticed a significant decrease in scans when returning a root prompt when I did that. This was also in the mid 2000s so who knows how things would be in this day in age for a reduction in scans

So it was a fake root prompt which tricked the bots into believing that they logged in successfully but in reality the prompt could do nothing on the system?
