After The Trade...

After the trade was completed, Navy walked out of spawn and suddenly was swarmed by noob traders wanting his keys, the trade noobs offered garbage weapons.

I spend a lot of time on TF2 in trade servers, and there have been times when this kind of stuff happens, random people will send me trade requests and ask for my keys. I never state I was selling them or anything (I never usually sell my keys only if I really need to).
