why can an unregistered bidder bid on your items?

[vintage2201]

Just curious recently someone bid on one of my items without being a registered user and never paid

they also bought items from other sellers without paying I only know they were unregistered by a email from ebay

I applied for a upi strike and recieved a fee refund anyone else have this problem?

There's a difference on eBay between running a business and being a business seller. Business sellers, it usually says somewhere on their listing, even on their feedback page I think. Once you've converted to business seller status, you can't change back. You lose some of the perks that non business sellers get, like the 3 free relists. For most people it's not worth becoming a business seller. They are far better running their business as a regular seller.
