I don't think I understand the point of this? It's a collection of page text and attachments scraped from (mostly) commercial projects, not a schematic catalogue?
The value of the site is the schematics. Everything else is just a bunch of text pointing to the schematics. The schematics just link to the build docs hosted by PPCB (or whoever). When you visit the schematic, you actually go to the PPCB website. The traffic to PPCB is paid by PPCB.
