For Steam Trading The easiest way that I avoid scamming is by not trading at all. I don't really care about trading items with other people, it's never really mattered to me. There are some people who still approach me though with the intent to scam me. So here are some tips, - Don't click any links provided by the person proposing the trade. (Unless you are 100% sure they are trustworthy) - If you go through with the trade, and they request a third party for the trade, don't bother. - There are a lot of spam bots that send incites to everyone that has an inventory in a specific game. So don't add anyone you don't know well.
