I don't add anyone myself if you want to be friends you have to request yourself. I don't accept players with steam lvl 0 and private profiles.
I block every one who message to add their other acc for trade.
If u want to trade leave your offers i will concider them.
I don't like being disturbed then I'm playing so i will answer your massages only after game.
I speak english and russian so feel freely to use with language is more suitable for you.
