Unusable seller?

Miscellaneous proof

Classifieds at the time of this listing: https://backpack.tf/stats/Unique/A%20Well%20Wrapped%20Hat/Tradable/Craftable

2x 15 ref, 1 painted

4x 15.33 ref

1x 16 ref

1x 17 ref

Countless listings at 1 key, however, several listings are either bumped or 3-5 days old, implying that 1 key flat is too high of a price.
