Tough decision with cublogs.org

We have had 171 blogs setup on cublogs.org since we started it.  Of all of those blogs, only 7 have actually been setup by real people or credit unions.  The rest have all been spam and it is becoming a slight daily annoyance.  The basic idea behind cublogs.org is to remove the perceived technology barriers of blogging and enable credit unions to use a great blogging tool free of charge.  However, it seems that more spammers are using the tool than CU’s right now. 

So here is what I’m thinking:

  1. Leave cublogs.org up as it is, with no changes, and just deal with the spam.
  2. Kill WordPress Mu, the engine behind cublogs.org that lets people start their own blog on fly.  Instead, offer WordPress expertise, blog hosting, and general help, for free of course through the domain.
  3. Kill the whole site and not renew cublogs.org.
  4. Morph cublogs.org into some type of community listing of all credit union related blogs.  Open Source CU has the best blogroll, but why not use the domain as a massive community generated list?  I’m not sure the best way to do that, but that’s why it is just an idea.

What are everyone else’s thoughts?
