I do try to stay under the radar as much as possible. I don't post the URL
anywhere. I'm not even listed on the wiki as a Jabber server, relying on
word of mouth. And what fun is having an XO chat server if other folks
can't join in? Also, playing around with Moodle and Statusnet and stuff
like that is a lot more fun when there are other users.

Great! I'm very glad to hear that.
I still had bots with empty user agent strings originating from the UK, US,
Italy, Spain, etc. And I wanted to go ahead and block all bots who identify
themselves as such.
I put this in /var/www/html/.htaccess
SetEnvIf User-Agent ^-$ block=1
SetEnvIf User-Agent ^$ block=1
SetEnvIfNoCase User-Agent "(bot|spider|spyder|yahoo)" block=1
Allow from all
Deny from env=block
Now all blank user agent strings and even Googlebot get a 403. (The User
Agent Switcher addon for Firefox is quite handy to test that with.) I'll
probably have to add to the user agent list, but that should take care of
most of it for now.
