Something's fucky with the "Filter by user" field in the modlog, especially if you paste someone's name in there (which is usually how I use it, to try to figure out what happened to get someone banned.) Just as a random example, if I click the field, check the box to "show banned users" and paste "SimMs" in the box, I get no results. If I delete the text and type the name in manually, it shows the user. Sometimes it seems to fail to find people randomly even if I type the name.
