-I unbox TF2 hat crates and cases, which cost $2.50 to open.
-I get an Unusualifier (which add a decal to some other thing that costs at least $5) from a hat case, and buy the item associated with it.
-A guy on Steam who duplicated another guy's Steam account and made their inventory private offered me 20 keys (for opening cases) if I sent the "Unusual" item to him through a marketplace.tf bot; I told him I had no idea what marketplace.tf was, so he had me set up an account there to check the Unusual item's value on the site and then had me trade the item to him through the bot anyway. He also asked me for 90% of my other uncased stuff to the bot to "verify" it. That was roughly $100 down the drain, though according to the site it was only $65 worth of stuff anyway. The scammer offered to get the stuff back for me if I gave him my username and password, which I declined (at least). This guy remained my friend on Steam for two weeks after the scam, until I realized he was a duplicate and he ditched my ass.
-Five days after the first scam, another guy who paid off a couple of people to put "+rep

" on his profile offers me $20 in Steam Wallet cash for the remaining 10% of my uncased TF2 stuff. I'm kinda skeptical, so he goes ahead and sends me screenshots of another account that he's going to use to purchase the Steam Wallet code to send me, since his account is in the middle of nowhere and can't buy Steam Wallet codes. He also has me give the stuff to a bot. I realize that the screenshot account is from the Philippines, which has NO Steam Wallet service at all, but he still insists that he'll get me the money. He then says halfway through that he's going to need some more value, so I offer him ALL of my Steam Trading Cards, though he said he only wanted 8 or so. He then blocks me after I unload everything onto the bot, and I throw a temper tantrum on the Steam forums about how "+rep

" does more harm than good.
So yeah, I'm fairly gullible.
