It’s getting serious out there on eBay.

A man who bought a used cellphone – and returned it for a refund but badmouthed the seller – now may have to settle a cyber libel suit.

Returning the used merchandise wasn’t enough for Chris Read, of England. He told off seller Joel Jones in the “comments” space, saying, “I paid for a Samsung F700 and got a Samsung F700V.”

Jones, a used-electronics dealer, took umbrage. Read got a letter asking him to admit that his comments were unfair – or else he’d have a date in court for “substantial” legal fees, plus $350 in costs.
