can an admin account be set to permanent “silent” mode?

[maxd]

We have the want/need on our forums to set an admin/moderator account to permanent “silent” mode, meaning the system would ignore that account's posts when it comes to the “Latest Posts” lists and so forth. These are maintenance posts that the readership have no interest in and don’t want to see in their “What’s New” and so forth.

Any recommendations for how to do such a thing?
