Now to prevent conflict

I've seen the sold, and yes it was traded away very quickly. That alone is not enough to suspect it to be a quick sale though.

1) "Time is only one factor used to determine a quicksell. If a hat sells within 1-2 days for its b/o in pure, one should be suspicious. However, since time to sell varies greatly among the type of hats (old vs new effects, misc vs hats, high tier vs low tier), this is not a reliable way to identify a quicksell."

The hat was sold in unusuals, not in pure for starters. The Honcho with Phosphorus effect is only 2 in the world. You can expect demand for a rare hat to be high

2) "Exception 2: Rare Hats

- The hat went to a collector or person who intends to keep the hat. A collector can be identified by looking at the person's trade history, item history of similar unusuals in the backpack OR if the owner has not resold the hat 1 month after the sale occurred."

Phosphorus screams Robo effect, therefore 1 sale is sufficient.
