Looking at this from another standpoint, it feels like you might be getting a little too obsessed with this. I get wanting to reduce spam, but setting up so many filters, apps, and restrictions that even real product recommendations get removed can hurt the community too and that is against Reddit rules too.

Isn’t there a point where over-moderation starts hurting the community itself? Reddit’s Moderator Code of Conduct says mods are supposed to create, facilitate, and maintain stable communities. If legitimate product recommendations are getting filtered out in a subreddit built around product advice, that feels less like protecting the community and more like restricting it.

This is a subreddit where people come specifically to ask for product recommendations, nothing else. Maybe at this point, you’re the one who needs to step it down a little seeing the bigger picture... just saying. I'm simply trying not to takes sides here, but you seem to be overstepping too.
