OPSkins Fake Trade:
A user will ask you if they could buy your item off of OPSkins at a certain amount of money. When depositing onto OPSkins, the scammer will send you a trade offer with a fake OPSkins bot and take your item.
The Middleman Scam includes three people. The scammer, the scammers friend, and you. When doing real money cash out or something equivalent, a scammer will ask to do a middle man trade. What happens is the scammer will ask you to add someone random and once you accept him, the supposed "middleman" will ask you to send your item to him in exchange for the money (or item) you're trading for.
Private Inventory Trade:
This scam involves a scammer wanting to trade his skins with you. He will ask you to check his inventory to look at his skins, but his profile inventory is private. There will most likely be a link in his description linking to an inventory. This will link to another user’s inventory. The scammer will be impersonating another user with the "same" profile as him. An easy way to identify a scammer like this is by checking their steam levels or asking the scammer to make his inventory public.
Real life money Trading:
A scammer will say that they will buy your item through Bitcoin or PayPal. What will happen is if you send your payment through Bitcoin, the sender may not be verified, and the payment will decline. Make sure to wait after the first confirmation before sending your skins, because this will resolve the issue. If you send your money through PayPal, they can chargeback the payment after you send the items.
Different game trading:
This scam involves two different games. Most typically the scammer will say that they are trading their Dota 2 item (or something similar) for csgo skins. Lots of the time the skin will be worth a high amount of money, but that's because of market inflation, meaning that the Dota 2 item (or similar item) isn't worth the amount you see, and it will not sell.
Lend me skins scam:
This scammer looks as a normal guy at first. You play some games with him, have a good time, become an internet friend. After some time, this scammer will ask you to borrow him some skins. After you send him those skins, he will block you and you’ll never hear anything from him again. Sure, it is possible that he will give you your skins back, but that’s a rare case scenario.
Cross game trading:
This scam usually happens with Dota 2 items. A scammer will send you a trade offer with your expensive items for his item, that is a lot more expensive on steam’s community market. This item’s price on steam market is manipulated. Dota 2 has a lot of items that have 0 value, and only a few people own it. These people put this item on market for a lot of money, so when a user checks the market price in trade, he will see a high price. But, if a user opens this item on community market, he can see that there are only a few of these items on market, and 0 sold in last 24 hours / 7 days.
Fake Gambling Website:
If you receive a random friend request from someone, you should already be suspicious. If someone adds you and asks you to gamble on his/her website this should be a red flag. When the scammer adds you, they will tell you that they aren't able to play on the website since they're the owner and that if you play on it, the scammer can "rig" it for you. After you deposit onto the website, your skins are gone.
The CSGO Community has very known Youtubers/Twitch streamers who upload/stream constantly on Counter-Strike and with this being known scammers will take advantage of players by pretending to be those well-known Youtubers/Twitch streamers. They will ask for a skin so they can make a video and will just end up scamming you.
Fake owner of a trusted website:
This type of scam is again one of those most obvious scams out there. A scammer will add you as a “Hellcase admin”, for example. He will tell you that you have skins, that are low stocked on their site, and that they want to buy them out for credits on their website. You’ll receive a trade offer that only includes your skins, and says: “After accepting this trade, you will get x€ on Hellcase.com”. Most of the time, x is a lot higher that value of your skins.
Impersonator of your friend:
A scammer adds you and offers you a good deal for your skins. He wants you to send your skins to your friend, just to check if “you can trade them.” Then, he renames his steam to a name of your friend’s steam and changes his steam profile picture to a picture your friend has. Afterwards, the scammer will write you to send him the skins, so instead of sending your skins to your real friend, you will send it to him.
QR Tipsport paysafecard scam:
Scammer makes a post on a social network, for example Facebook that he is selling his skins for paysafecard. Price of these skins seem good for you, so you add and contact him. When you contact this scammer, he will tell you that he only accepts paysafecard from Tipsport. This is because only Tipsport paysafecard has a QR code. Then, he will tell you to send him a screenshot of that paysafecard with hidden code, hoping you do not hide the QR code. If you do not hide the QR code, the scammer will scan it and take all money from your paysafecard.
Skins upgrader scam:
This type of scam is one of the most obvious scams out there. Scammer adds you and tells you that he can upgrade your skin to a better one. Who doesn’t want better skins, right? He will usually tell you, that he can upgrade your low to mid-tier skin to a high tier skin, for example a Karambit Fade. When you think about it, why doesn’t he upgrade his skins instead of upgrading skins to a stranger? Well, because this person is a scammer. Nothing like “skins upgrader” is real, and these people will scam you.
