Is OkCupid Green Dot accurate?

How accurate is the green dot on OkCupid? No, it isnt accurate at all. Thats why it was taken off the main site because it would show the green dot for an hour after the person had logged off, and if they were using mobile it shows when their phone polls for messages even if they are not actively using the site.
