Please stop being hysteric.
We have added a version check to this component as a service to you.
There is absolutely no private informations which are sent to Joomlapolis during that check. It's only a standard http-request.
To be able in the future, if there is a big security threat for instance for a given release (this has not been the case up to now) to display a more visible warning to the admin, the request has the CB version in its request, so that the reply can be corresponding.
Part of a standard http-request is the referrer (which in this case is the mod_config_live_site).
This request is done only for the site admin in the backend when looking at the CB configuration. Other components and Joomla itself provide the same kind of services.
Nowhere else and Nothing more.
