The block to prevent further bids/offers/purchases has always been immediate but the block on messaging used to take 90 days following a transaction to take effect. I believe as long as the "Don't allow blocked buyers to contact me" box is checked in buyer requirements that now also takes effect immediately.</P><P>&nbsp;</P><P><a href="https://community.ebay.co.uk/t5/user/viewprofilepage/user-id/1987414">@kheate31</a>&nbsp;- do you have the box stating "Don't allow blocked buyers to contact me" checked in your <A href="https://www.ebay.co.uk/bmgt/buyerrequirements" target="_blank" rel="noopener">buyer requirements</A>? I believe that option is unchecked by default. Also, even if you block a buyer this way they can still communicate via a case but once the case is closed they can't communicate with you any further.</P> Thu, 09 Oct 2025 15:31:22 GMT 4_bathrooms 2025-10-09T15:31:22Z
