It means you have bought an item and did not pay for it
and the seller filed an upaid item disput.
After you do this twice most sellers (((( not just the ones you failed to pay)))) have blocks in place where any bid you try to make will be rejected because you have
2 or more unpaid item strikes against you in the last 12 months.
Normally after 3 or 4 of these Ebay will suspend your account.
