Tech Target is a spammer

I am a reader of the ServerSide.com – THE resource for Java development information.
Still, after registering ages ago to the site and the utter collapse of the 1and1.com (my email provider) spam filter (which still does not work) I started getting tons of email from the ServerSide.com’s parent company, TechTarget about things I care less and absolutely not about. Their unsubscribe link takes you to a page that tells you that you are unsubscribed. It even sends you an email to confirm it. And then you still get their annoying invitations to events and conferences that they organize which I naturally do not want to get.
So Tech Target now counts officially as a spammer.
Bad karma unto you, Tech Target. You suck.
