One of my two is a notification from livejournal.com that my girlfriend
posted to her lj. The other is a post to a yahoo group for a local goth
club night, to which I have been subscribed for a while.

There are a number of reasons for the score generator to come up with this
result.

I have 29 hams that hit this. In reverse chronological order:

Looks like 18 are livejournal.com. 11 are notifications that there were
updates to the thread
http://www.diyelectriccar.com/forums/showthread.php?t=53001 which I had
subscribed to.

So, all of my hams hitting both of these rules are legit hams, where the
blacklists had false positives. I am very confident that none of them were
just exquisitely faked.
