You may want to consider not keeping logs, putting the <meta name="robots" content="noindex, nofollow"> tags in to stop search engine spider indexing, and to make the list and its archives private. No need to make it easy for them to find the out of context evidence they might need on any one of us. And since there appear to be a few high profile people on this list, it might help protect them.
