Only CPFs and Welcome Mails are done on SITE_DB instead of FORUM_DB.
Welcome Mails for good reason - they truly are per-site.
I think it's probably done like that with CPFs so that new satellite sites don't end up polluting the central site each time something new is installed, but it seems dubious - that should probably change. For now though, I am modifying the admin_cns_customprofilefields module to set FORUM_DB:=SITE_DB for the run-time of that module, to avoid serious confusion.

However the problem is uploads won't end up on the central site, because the satellite has no access.
