I dunno if this is the right place to put this, but my "Beat Elmo - Bert" beat the world record, yet was placed in last place. Is this a glitch?

No, I absolutely did. It's in the video as well as on the website.

And now it's been rejected for modding/emulators even though I didn't mod or use an emulator.

It took 6 real seconds for your in game timer to go from 1 to 2. So you were able to put in 6 seconds of inputs in 1 in game second, while everyone else puts in 1 second of inputs in 1 in game second. See the problem?

Ah. That's just because of my garbage laptop. I didn't know my bad frame rate would benefit me when I was holding down one key.
