Public Lab's full moderation policy is located at, the portion regarding mailing lists is included here:

Please treat our mailing lists as a place of respectful conversation. Our lists have moderators to ensure civility. Moderators review the posts of all new members before approving them to post automatically. Some existing members may be placed into moderation if their posting pattern changes such that it violates our list guidelines (see below):

Before you are placed into moderation, you will be notified on the pertinent list.

List management

As the # of topical/local lists grows, some consistency in spam handling, joining policy, and naming will be very helpful. Also, we want to just be careful not to let research-related conversations fragment. To this end, each smaller list has at least one moderator responsible for moving conversations to the appropriate list and "bumping up" topics of general interest by saying "Wow! Please take this extremely interesting conversation to the main publiclaboratory list!"
