Please note that this is my personal blockfile and I'm surfing on some Swiss websites. Maybe some of the advertising filtered here are of interest to you, so look at it first and delete the entries you don't want to be filtered. I'm relatively conservative though... Some of the entries are specific to Switzerland and probably not so interesting for you.
12. January 1999: I included the blockfile from Stefan Waldherr firstname.lastname@example.org, which is always available from http://www.waldherr.org/blocklist.
Comments and additions are welcome.
Here's the blockfile.
