Perhaps there can be an option to block certain content. Such as a blacklist, which blocks all products with certain tags. That being said, I personally wouldn't use it, and I am unfamiliar with the system that is used to run the marketplace. Perhaps there are options or plugins for that system that allow this.

However, for such an invasive change in the way the site works, I would say that at LEAST 50-60% of the users of this site should wish for this.

@McGrandpa Please do realise that if this is something that will have to be custom coded into the system, this will bring downtime of the site, possible (likely) introduction of bugs and other inconveniences to you, me and other users. I do very much understand your point of view, as I am a devoted DS user, and have absolutely no interest in Poser-only items. However, I see sufficient ways to find what I require. It may be a few more clicks, but that's a minor effort compared to what needs to be done to implement this.

I do not mean to bypass admins or mods, or make suggestions or assumptions that are incorrect. I am just replying from my experience as a senior programmer.
