How to aviod: Phishing, Scamming, or being sharked

Hi i was just wondering if you know If delfy is a scammer because he is saying that he is going to pay for my unusual through a trade offer (real money) and I don't know if this method is real. I know he isn't the real delfy, even though he has claimed to be.

When I was phished and my account was hijacked I think he was hijacked afterwards cause all of my chats had a phishing link in it

Plus, Jonahk9 isn't a scammer I traded with him before

http://v1.steam.hlxgame.cc/id/jonahk9 he is a trade scammer also when you report tell them to send all of his items to me because he has most of my stuff

Guys i lost my account to a phisher and I'm mad at myself and Free Gifts Forum is the reason to blame

I think i found a scammer his username is Free Gifts Forum i will update if i was scammed or almost
