Returned a few purchases on Amazon? Then take note of Greg Nelson, a computer programmer who saw his account canceled after he returned 37 of 343 items, the Guardian reports.

“I could understand if there were evidence that I had somehow tried to abuse the system, but I haven’t,” says Nelson.

He claims the returns were all justified, but Amazon UK simply axed his account and deleted any remaining gift card balance.

So what constitutes extreme? Amazon UK allows customers to return items within 30 days but refuses to say how many returns are too many.

Tech Walls advises customers to keep return rates at under 10%—a threshold that may explain Nelson’s canceled account and those of two others (described in this tweet and this posting on Amazon).

“Making a new Amazon customer account, however, remains a simple task,” says Inquisitr. “A lot of individuals will just use a spouse or family member’s account after their account is closed.”
