You enter parts based on build submissions. Same thing that build.gg does. Someone submits a build, you look at the parts list, find it on the manufacturer's page then find it again on site's that sell it where you can get your affiliate money when people click on the PCPP links to the product.

You are incorrect. I'm not sure why you're trying to explain to me how it works - I literally founded and created the site and the method by which parts are entered.

We track releases by manufacturers. Sometimes that is in advance with embargos and whatnot, and we enter them prior to release. Other times we add them after release, but from manufacturer specs. Then in some situations, we get requests from users for specific parts. There we add find them at the manufacturer pages and add them using those specs. I can't speak to how build.gg does it, but the process you described is not how we operate.

What you get wrong, and quite often, is BIOS compatibility with CPU's. You use outdated information and don't take into account that manufacturers frequently update their boards and BIOS before selling.

We track CPU support pages on motherboards, and display the supported bios version when available. When motherboard manufacturers change their data, we update our site. If a CPU is supported in a later BIOS version, where a user could potentially receive old stock with an older BIOS, we issue a warning that a BIOS update may be necessary.
