This doesn’t seem like a genuine discourse, but purchase suppression can occur in batches. So that purchase data may not get fed back into all the advertising systems for days/weeks if it’s using a poor set up. For example, sometimes for suppression brands literally just export a csv of customers and upload it to google. If your marketing guy does it once a week.. I’d assume eBay’s doesn’t work like that, but it’s possible. Also possible they just don’t suppress recently bought items !
