Today I got this spam message:

From: Tessel van Leeuwen <tessel@waag.org>
Subject: Invitation: Join the Apps for Europe competition and win 5,000 euro!
To: undisclosed-recipients:;

Hello,

I'm writing to you because I found your email address on the website, http://act.useperl.at/apw2014/wiki?node=HackaThon, and I would like to invite you to enter the Apps for Europe competition: ... <snip>

There are a couple of things about this I find interesting:

1. As far as I can tell, my email address is not on the linked page.
2. The message has no visible recipients (so I guess my address was listed in BCC).
3. I've never done anything with apps.
4. The Austrian Perl Workshop was 2 months ago. Why harvest the hackathon page for email addresses now?
