/bbpress/bb-admin/includes/defaults.bb-schema.php

is where the table names are all set. But changing the names there is only going to change the name of the tables that are created. You would need to change every reference to a table to this new uppercase name. I can’t imagine how difficult that would be or what would happen with any plugin you install or what happens when it’s time for an upgrade.

What host is this that changes the table names (not the database name) to uppercase? I’ve never heard of such a thing. Is there a page on their site or an email from support describing their policy?

It’s ok to have a database name in uppercase, since you only reference that once, but tables names being restricted to uppercase sounds like a very strange thing to me.
