If I have any valuable items in my inventory I am NOT interested in trading ever. Any valuables I have are from dumb luck and I am not an active trader.
I am however an active shenanigan man and will accept most friend requests just to waste your time and frustrate you if you are a scammer before I report. Your best bet is to not even try. If you do want to trade put up or shut up, steam inventory only, no opskins, no checking validity, nothing no third part things whatsoever, and your profile MUST be public and inventory must be public. I will not listen to backpack.tf links as those are easily faked.
