I have over 4000 posts and NONE are spam. The problem appears to be their algorithm. Yesterday I posted over twenty stories from the Leipzig Computer Fare Fact sheet series. Apparently others published the same Fact sheets (perfectly OK).
Digg checked the duplicates and accused this site of copying others work - they're so dumb they cannot see the differences. After I emailed them and received a standard reply informing me that they have deleted my account and marked the site as spamming...
This decision cannot be changed - apparently so I have removed Digg buttons from the bottom of my postings.
Sorry, to all those people who Digged my stories - feel free to contact Digg and complain here...
