I never understood how that is valves problem tbh. That’s like being mad at football players for sports gambling. The second you have a somewhat open market, some people will abuse it.

Also, what’s valve supposed to do? They bab the trade bots if they can find them, they have sued the operators of those portals in the past - so what do you realistically expect from them now? Completely close the market just so some people can’t gamble anymore?
