Sellers should beware of spam commenters recently leaving emails or phone numbers wanting to complete transactions outside of the website. I’ve gotten about 30 of these in the past week alone. I googled one of the phone numbers and it was connected to a check cashing scam: where someone sends a fraudulent check for more than the item’s value and then sends someone to collect the item and the “leftover” from the check. The check turns out to a be a counterfeit, which means that the seller’s bank is going to hold you responsible for the full amount. It’s an old trick but still ensnares people in the 21st century. I know these kinds of scams are prevalent on Craigslist and classifieds, but it looks like they just discovered this site too. I mostly got these offers on my most-expensive items, over $100, where it would not seem unusual to deal in 3- and 4- digit dollar values.
Be vigilant, fellow sellers.
Personally I think this influx of spam is another reason to allow sellers to delete and/or block unwanted comments.
