Is automating CSGO tradeup contracts considered a illegal activity

[VidKal]

I have been working on a bot that would do tradeup contracts for me. I am using steamkit to connect to csgo GC. Lately I have been thinking if maybe it is somehow againts Steam policy. Does anyone have a clue? 
 

Thanks in advance :)

I don't see why it would be.

Its not detectable, VAC only checks when your in a VAC secure server, not while in the main screen
