Spam reduced in Wiki

We had some more spam in the softwarefreedomday.org wiki. I have begun to block the IP address rooms of those who continue to spam the wiki and have been successfull to exclude all that air traffic spam that plagued us the recent weeks. We will not have any problem with wiki spam once we will upgrade the MoinMoin wiki to a version > 1.8.0 after he SFD in September. We chose not to do it, because this would also include a syntax change, which would  not be so nice for those who have tought themselves how to deal with the current markup. But for 2010 we will make the switch – and btw. the new Moin syntax is more similar to MediaWiki/Wikipedia because it is based uppon ideas from Wikicreole.
