Not counterproof so much as showing that the above links ARE NOT good proof, if proof at all

Selling

http://www.tf2outpost.com/trade/9397680

Only 19 views, going to guess this guy doesn't bump very often

http://www.tf2outpost.com/trade/8846411

last bumped 6 days ago, again going to guess this guy doesn't bump very often

http://www.tf2outpost.com/trade/9541025

1 day isn't very much, and the 22 view count makes it more clear that the above guys didn't bump very often

Buying

http://www.tf2outpost.com/trade/8611657

Quick Buying, should not affect price

http://www.tf2outpost.com/trade/9239874

Specifically says that he's buying a quicksell

http://www.tf2outpost.com/trade/9377200

Quick Buying, reselling in this trade

http://www.tf2outpost.com/trade/9546792

So realistically you have 1 piece of solid evidence there, link 3 of buyers which appears to be a guy quickselling his.

Downvote, sorry.
