PinkiePie's parent is a colossal, psychologically-abusive douchbag.

I caused the results of what is written in this letter, and feel quite colossally guilty. I had not realized just how psychologically abused this girl was (was this an attempted suicide? https://bitcointalk.org/index.php?topic=41901.msg509961#msg509961), or how dangerous and extremist her father was.

If you live near Waterloo, Iowa, and can manage to quickly track down the residence of a 17 year old girl named Ayn, I will personally pay you to buy ALL of the pony stuff her dad is claiming to want to liquidate, and to have it shipped to my house to store. Contact me personally if you can help.

Thank you.

Excellently performed troll post! Kudos!
