Comment 6 for bug 1614403

What about using akismet only for registered users when they wright her first x posts/topics?

We could then add some text to the templates, like: "This is your first topic/post on widelands.org. To prevent spamming we use the akismet service [link]. Therefore some information (your comment, IP-adress and Browsers user agent is sent to this service. After x verified posts/topics the akismet service isn't used anymore if you post some content."

I believe most of the currently registered users are safe, so we do not need to inform them about this service, unless they haven't send x posts/topics.
