Every comment I make on Sploid ends up in a black hole (only visible to me and the person I reply to). It's unfortunate, since every once in a while, they could really use some Jalop dropped into the comments.
It's really for the readers, not the editors - since they'll leave errors in the story.
I just figured out my black-holeness when I started replying to the Kombi story.
Hell, even the "My sister makes $3456/week" spam posts show up in the "show pending" view.
