Something very weird is going on. Someone is copying existing weblog designs to set up 'dummy' sites on a variety of domain names, apparently to increase the hits/PageRank of some central site (there's a hidden link at the bottom of each site). Observe:

(I'm using javascript: to link to the copies to make sure they don't get any PageRank boost by my mentioning them here.)
All the fake sites have an ip-address in the range 141.85.3.* and are being spammed as fake referrer urls to a number of real weblogs (mine and Knurpslog, to name two).
I'm currently successfully filtering them out of my automated referrer list by checking for
$REMOTE_ADDR != '217.73.164.106' && !strstr($REMOTE_ADDR, '141.85.3.'), which seem to be the hosts sending the fake referrers.
