432722 is a bot, shoulden't he be removed from the 'other monks' widget. I know gods have done this before, and this isn't a very big issue, just making note of it.
To explain the 'ticker' login mentioned by tye, you can prevent your username from appearing in the other users nodelet by adding a 'ticker=yes' parameter to the login URI (or to the POST parameters). From what I remember, I believe this just adds a character to the end of the login cookie (a 1 ("one") or an excalamtion point, I can't quite remember, and I cannot test right now). So each time you fetch a page from perlmonks, it sees that character and doesn't update your 'last access' date field, thus shielding you from the other users list.
Speaking in the CB bypasses the ticker login/cloaking function. Also, if you are cloaked you will see a '#' mark in front of your name in the titlebar links, and you will see different text on the CB submit button (i think it says 'decloak' instead of 'talk').
No, the gods haven't. The bot wrangler needs to use a 'ticker' login if they don't want the bot to appear in the "Other Users" nodelet (which also prevents the bot from 'earning' XP for 'logging in').
