but i did this on C# and steamkit for idle cases, 6 months have passed and didnt get no one VAC ban. But I understand that steam can ban everything at once

Hi. How send CInventory_ConsumePlaytime_Request using ur lib?

If player isn't in you friend-list you cant get player profile from non-prime account. but you can try it with account with prime status

It's possible, you just need process ClientServiceCall msg, when you start csgo. Game send VAC module that collect info about your PC, you need save it, run with parameters what receive in ClientServiceCall and send to steam in ClientServiceCallResponse
