You never stated any rules, so... [Insert what you just said].

Mhmm.

The word "Only" was added later. Besides, that could easily be misunderstood.
"I did it in only 500 frames, how about you?"
Y'see? I'd personally recommend that you state "Must be in 500 frames or less",
because that can't be misunderstood.

Edit: This is what your post actually says:

Looks more like you said that you got 12 in 500 frames. Keep in mind, i don't want
to offend you in any way, i just want to make sure that no more misunderstandings happen.

*Doublebump*
Sorry 'bout it, but thanks to PlayerID666, a total self-dismember has been made
in 500 frames :O
The original 19 dismember suicide made by me is here, and the
total self-DM edit by 666 is here. And it's legit.

Jesus Fu**ing Christ.

That's the most epic replay I've ever seen.
