One of the constant anti-spam measures I take around here is changing the names of files that are used in spam runs. Security by obscurity should be no use at all, but it is surprisingly effective. Normally you don’t see this because the spammers want files like the trackback scripit that you wouldn’t load. But recently they’ve been for no apparent reason repeatedly loading up an old paper, namely this one
just so they can say that some spammy site linked to it. Very odd. Anyway, the name of the file changed so if you’d linked to it, please change the link.
