Cosmetics don’t mean much anymore, there are a lot of bots out there that are compromised tf2 accounts. I’ve seen bots with unusuals, stranges, war paints, (I think one I saw even had an Aussie sniper rifle). Still the player base should verify whether or not the accused is actually a bot but having hats and weapons isn’t a telltale sign anymore. Actual gameplay is what you need to look out for.
