The term social network means any resource, where content can be created by users themselves: completely "social" resources such as vkontakte.ru and odnoklassniki.ru and also any forums, public blogs and dating sites..

The content, which is posted in social network as private (user's profile, photo, video, community or group, created by user etc.) is the same user's property, as free hosting website, so the user accounts for it according to the general rules, plus extra rules:

• it is forbidden to post any content, which is contrary to the general rules of social network or concrete group/community
• personal user's pages are per se different sites, that's why all rules are applied to them, first of all spam prohibition on outsider pages
• if the account is wittingly created for advertisement (public advertisement in profile, photoalbums, blogs etc.), it is forbidden to leave comments to this account, to take part in voting, to visit other user's profiles and also all possible ways of getting this account to pages of user's lists or resources, without their personal wish. It is also forbidden to use wittingly false keywords for attracting users in your account or content (such as free porno or windows crack)
• the account is banned without payments, after the first complaint of owners or official moderators of social network or separate community/group, where the advertiser's account was participated.

Notice: if you are the official advertiser or the owner of social network, the prohibitions, mentioned above, don't apply to you.
