webvisum privecy policy (you should read!!) : " If you contribute to the WebVisum project, you are publishing every word or piece of code you post publicly. If you write something, assume that it will be kept forever. This includes page element tags through the extension, articles, code, user pages and talk pages. [...] When you edit any page on the WebVisum site or enter tag a page element using our extension, you are publishing a document. This is a public act, and you are identified publicly with that edit as its author. [...] If you have not logged in, you will be identified by your network IP address. This is a series of four numbers which identifies the internet address from which you are contacting WebVisum. Depending on your connection, this number may be traceable only to a large internet service provider, or specifically to your school, place of business, or home. It may be possible that the origin of this IP address could be used in conjunction with any interests you express implicitly or explicitly by editing articles to identify you even by private individuals.
