I as a seller have this issue at least once a week. One that caught my attention was from a buyer

 I wasnt scammed in anyway. The buyer just won the bidding and never paid. So had to submit a UPI.

What do they get out of this I dont know. So makes me wonder why they bother doing this.

I wonder how many more ebay accounts this user has.

Enough said, ive now learnt to list items blocking any users who have 2 UPI's against them. Lets see how things go!!
