In the past, I’ve seen most boards have a two tier moderator structure, I’ll refer to them as Tier 1 Volunteer and Tier 2 Professional.
Tier 1 Volunteer moderators are purely unpaid volunteers. Their primary job as moderators is to keep the community boards free of spam and other junk posts.
Merging duplicate and/or similar discussion threads, and otherwise maintaining a clear organization of information on the community boards is also their responsibility.
Tier 1 moderators are sometimes responsible for moderating inappropriate behavior on the boards, typically this occurs as a moderator gets more experience and a better feel for what to do and when at the guidance of a Tier 2 moderator. They sometimes have the ability to edit user’s posts on the forum to remove content that violates community policies, such as links and language.
Tier 1 moderators do not typically have access to any personal information such as phone numbers, email addresses, mailing addresses, or anything not available to the general public of the community boards, except for user posts that have been hidden due to violations of community guidelines (or moderator discussion areas).
Tier 2 Professional moderators are often employed by the organization, and are often responsible for writing community guidelines and making sure that the community reflects the company and is an open and inviting, and helpful place.
Having not been a professional moderator, I am not entirely sure of what additional information professional moderators typically have access to, but email addresses and IP addresses are likely to be included. Tier 2 moderators would be able to send password reset emails for users, and block bots and other malicious actors. For smaller organizations, tier 2 moderators often have additional IT Tech Support responsibilities which may require them to have access to additional information beyond email and IP addresses. A Tier 2 moderator typically has the ability to merge duplicate content, edit user’s posts to remove links and language, and delete or hide content from the public or otherwise manage membership and access to specific areas of the community (Blocking, VIP Areas, Moderator areas, etc.).
