*Introduction [#se99413c]
The PukiWiki engine is quite nice since it uses only PHP and is quite simple to run on any server.  In the far future we may migrate away from that system.  In the mean time, we are using this method.  However, it is extremely prone to spam from company propaganda owing to the fact that there is no restriction on creating new pages.  I hope any users of this website only wonder, "Why is this a problem," rather than actually seeing the problem.  However, I have wasted a number of hours removing obvious spam from another PukiWiki I admin, and I needed a better way to use my time!  

*Stopping spam [#s4d1fac3]
A spam filter is now in place and tested to work.  We may expand the URL banned list if problems continue.

*IP Logging [#x13a40f1]
IP addresses are now logged in the [[iplog]] and displayed for each modification.  

**Banning [#m04db02b]
Guilty offenders have their IP addressed banned in htaccess.  Warning to people spamming this page from Ukraine and Thailand servers: I can block you [[by country:http://www.countryipblocks.net/country-blocks/htaccess-deny-format/]], so consider it a warning.  That would be extremely regrettable to ban countries even if GemStone may not be popular there.

*Watching changes [#xe2d1d68]
E-mail notification to [[Kaldonis]] is now enabled for every page change, including the IP address.
