I think apart of what elmo says there are bots buying and surely ppl with macros.
Was on the Hat Trading page yesterday and 1 painted (is the orange color maybe Mann Co. Orange) Cold Front Caparacce was bought for 1 keys and 30 ref aprox (dont remember the exact ref amount), then a moment later i checked BackPack.tf for that item, the very same item (paint and everything) was being sold by a bot, a very rich bot #440 backpack aprox for 12.4 keys. i created the forum account for this stuff ngl, cause if you manage to get some good stuff it gets yeeted in milliseconds and sometimes is infuriating
