How often do you verify games?

It’s not that I’m upset or concerned, not at all. I’m just curious. As Vic says, it’s useful to “model the consciousness that is different from your own,” so I decided to ask the community. I spent two years managing the ranking on the Portal, and now I’m monitoring the reports on my website with automatic accounting. Why does it happen that an unconfirmed game remains listed for a month or even longer?
