I was surprised to see defcad.com come up in some searches I made. It's a shady site; they're known for selling stolen CAD models and scamming users by passing off unusable CAD models as working projects, as well as doxxing and blackmailing people. For what it's worth, the owner is also a registered pedophile sex offender.
For these reasons I would argue it should be de-ranked for the sake of user safety in case anyone would stumble onto the site. There are countless safer and better alternatives amongst the search results.
TL;DR;
De-ranking defcad.com would improve user safety and search result quality.
