I've seen that bug before, but I doubt that happens at the same second. User "bitart" isn't in my list of people who sent Merit twice in one second.
It's obviously possible to do it slower than 1 second which would explain bitart's absence from the data. I was just thinking it would be odd if there was another bug that caused the same thing.
Anyway thanks for doing this, the site stats cutting the lists off at 50 is very limiting. I'm also looking forward to the ranking stats. That'll not only find the cheats but also show that people can still rank up if they deserve it.
