I left a feedback for a seller that said-- slow ship otherwise fine-- something like that.

I received 2 negative feedbacks, i bought 2 items:

"WARNING SELLERS A REAL PEST! LIMP-WRISTED ANT-AMERICAN LEFTY.BAN HIM!!!"
"WARNING! SELLERS! THIS LIMP-WRISTED MORON LEAVES SEDITIOUS POSITIVES!"

The guy got 2 positive feedbacks and i got 2 negatives. Guess what? There isn't ANYTHING that can be done.

Morale of this story? Don't leave feedback until you get it from them first. If they don't leave it, don't do it either.

Don't leave a negative, i promise.
