Adblock rule to block g+ / twitter / etc.

Looks like this rule works to blocking facebook domain, when not visiting the facebook domain (ex.: "like/share" etc. buttons on other pages then facebook): ! don't allow facebook outside facebook.. ||facebook.com$domain=~www.facebook.com ||facebook.net$domain=~www.facebook.com ||fbcdn.net$domain=~www.facebook.com facebook.com###appsNav facebook.com###pagesNav facebook.com###groupsNav facebook.com###pagelet_friends_online facebook.com###pagelet_bookmark_nav facebook.com###pagelet_rhc_footer But how can I block completely twitter / g+ / etc sites with adblock rules? (Is this really effective, or it only makes me not to see the fcb buttons/etc.)?
