It seems like there are many secondhand trading scams lately, so I'm writing about this.
I've written mainly about the elements I personally observe or confirm when doing secondhand trading.
I hope it's helpful to many people.
==Secondhand Trading on Dosa==
- Try not to post buying requests (looking for).
(From my experience, more than 90% of the time only scammers (or fraudsters) contact you. Even if it's a bit inconvenient, it's better to directly search for marketplace posts.)
- Check the seller's member information (if private, check all posts).
(If there are almost no comments or posts written besides the sales post, or very few (low-value comments made to appear active), you can identify and avoid accounts that either just signed up or were created specifically for scamming purposes and have no activity outside of selling.)
==Beon*Marketplace / Jung*Country and Other External Secondhand Trading==
- Don't post buying requests (Same as above)
- Check seller reviews, past sales history, and Carrot temperature
(I apologize to those doing secondhand trading for the first time, but personally I avoid trading with people who don't have transaction reviews or transaction history. Thanks to this, I've never been scammed.)
==Both Dosa and External Secondhand Trading==
- (Chrome browser only) Right-click on the photo in the sales post and try searching with 'Google Lens'.
(If the exact same photo appears on a different site other than Dosa, you can confirm it's plagiarized unless it's from the same seller.)
- Check phone numbers/bank account numbers using Durcheck.
(It's true that scammers who intentionally scam keep changing burner phones/burner accounts to continue scamming, so verification can be difficult, but in any case, this is the most reliable way to filter out scammers.)
- Don't trade through external links (external sites).
(If someone asks you to go to a strange marketplace you've never heard of and trade, it's absolutely 50,000% a scam. Just don't do it.)
- If possible, try to trade in-person to also check the product condition.
(It's best to invest a little time and go directly to check the items to avoid stress from issues like undisclosed defects.)
- If you're about to trade (right before), try adding the seller's phone number as a KakaoTalk friend.
(It varies case by case, but it was helpful to me. In my case, the other person's profile was clearly a flower photo taken from the internet, so I immediately checked their phone number with Durcheck and found it was a number with fraud reports filed. If there's no KakaoTalk profile at all, you could say it's even more suspicious.)
If you have your own method of filtering out scammers besides the methods I mentioned, please share in the comments!
Praying that all secondhand marketplace scammers go to jail, I'll stop here.
Everyone, stay safe~
