Spam killing Server
I do like the trackback functionality very much, but no chance, so I tell a similar story to others in the group.
In my case comments still are manageble - trackbacks not.
On my blog (now on Drupal 5.2) I do allow anonymous commenting but had to stop trackbacks.
The spam module is really very good in identifying spam und unpublishing it, that is the good side. I configured comments to have preview mandatory, there the remaining spam is managable for now.
