I might not know too much but I really think they are using my forms. I found
quite a few log entries. Here are a few.

And the
xpl.netmisphere2.com site has hacking information:
http://xpl.netmisphere2.com/ I think this outta be illegal!!
Looks like an exploit of a cross-site scripting vulnerability in your
join.php form.
http://xpl.netmisphere2.com/CMD.gif is the cracker's PHP
script that gets injected into your form, it's not an image at all.
You need to turn off that form until you can get a fixed version of that
application. And of course reinstall that system.
