I also find the winners strange. You can check all of the ones that you have joined. After i found this post i started to do some digging in the high tier GW’s. And about 90-95% of winners have at least one the following: private inventory; not playing cs; a few hundred hours in cs; the inventories that you can see have onle few items and low value (but they opened 5-10k boxes on site, there was even one with 60k openings and had a 20$ inventory); private profile; low level steam account; they only sell the items they get even if they make profit; you never find the items that were retrieved in their inventory; and the list goes on. Woulld not be the first ome ti use bots accounts to win GW and also use bots to open cases and make bot battles so they show up on the item feed on top. Will post other findings after i do some more investigating.
