FWP no respecting default user level settings

I’m using a WP network and all the incoming users are being created as “contributor” level instead of the default “subscriber” level, I believe this is the part doing the deed in syndicatedpost.class.php line 2388

// Multisite: Check whether the author has been recorded
			// on *this* blog before. If not, put her down as a
			// Contributor for *this* blog.
			$user = new WP_User((int) $id);
			if (empty($user->roles)) :
				$user->add_role('contributor');
			endif;
