It appears to be the Bible Students who still follow Russell's teachings.
From the website-
"Our purpose is to provide comfort, encouragement, friends and resources to our brothers and sisters in the Society who feel they are not permitted the liberty to freely study and inquire regarding Jehovah’s Word, without the fear of disciplinary action, disfellowship and separation from your family members. This website is a resource to help our dear brothers and sisters fellowship and study without fear of punishment."
"You are anonymous here. You can speak to other Jehovah’s Witnesses, former Jehovah’s Witnesses, Bible Students and other Christians. When posting your comments, you will be able to use a Pen Name. Your e-mail address and website info are completely optional. No one can identify you. No one can report you. You have a home and quiet place to pray and honestly investigate scriptures. It is not our purpose to indoctrinate you, but merely to provide you with resources for further study of Jehovah’s word. You are not alone. You have friends."
They also have a question and answer section, the link of which is posted below.
"The suggested answers provided to all questions below are based on and in harmony with the views of the original Watchtower Bible and Tract Society when under the guidance of Pastor Charles Taze Russell. Comments will often include a link to Pastor Russell’s own explanation. However, in any case, we leave your conclusions to your own personal study, prayer, conscience and the influence of the Holy Spirit."
