I just deposited 20 cs:go keys to the bot http://steamcommunity.com/profiles/76561198072510469
After it's done, i get a message from the desktop notifier that i declined the trade offer. The trade still gone through and the bot got my 20 keys.
I am scared shitless here that something has fucked up. The security code was the right one and all.
Here is a screenshot of my trade history
