I'm probably missing something or not saying what I was thinking correctly (or these stores you're mentioning have a way to spam or circumnavigate the algorithms). But in general I'm not worried that a creator created a white paddle, or mug or whatever. I'm not concerned the title says "mug" or "Pickleball Paddle". Anyone is free to create whatever design they want, and free to put whatever titles and tags they want. My concern which I'm calling a "bug" though it's quite possibly actually designed this way for some unknown reason to me, but I believe the design of the algorithm is not well thought out. There are at least two major issues as I see it.
1. Zazzle is in charge of what/who's stuff gets seen. This is their responsibility IMHO. Thus, they state we need to have good titles, descriptions, and tags to even get seen and sure, fair enough. They failed here as these products have NOTHING in the title at all. Just the default Zazzle added product name. They don't fit their own criteria for being returned on search results, so seems like a bug to me. They shouldn't be returned over of the many other products that have everything up to snuff. Sure, give them to the customer on page 999 or whatever but not page 6.
2. Zazzle has limited the amount to search returns on this user input of "Pickleball Paddle" where they themselves say there are over 67,000 items in the search result, while only showing 12 actual pages of returns. I call that a bug, but it can be a feature as well. But IMHO it's a bad user experience to limit the search pages to only 12 while saying the amount available is actually 67,000. How is a user supposed to find them then?
I'm not trying to step on anyone's toes, just trying to figure out who's supposed to get this kind of "bug" reporting so they can look into it. If they decide to do nothing, well OK but then there isn't much use for me to design any more paddles as they will never be seen it seems.
