In Germany it is not unusual that a company collets private information of their shareholders. A german public traded company has the possibility to sell "Namensaktien" you may call it "Name-Shares". A good example for Namensaktien is "Technotrans" a german leader in print-support!!!
A few years ago they changed their shares to "Namensaktien", which means that no longer a transfer-agent administrates the shares but the company itself. Each share is registered by the company with all necessary information about the shareholder to which the share belongs!!!
