Anti-spam people sending spam messages

So I check the Calstuff mailbox today (calstuff [at] gmail dot com) and see a message from

Hi there,

I would like to ask you to exchange links between yours and ours sites. As you probably know this will provide your visitors with valuable resources, as well as it would do for us. We can place your site in category of our resource page, suitable for it, and with a good Google Page Rank, easily accessible from our index page. If you would like to swap links please send me your website details, and if not, excuse me for wasting your time and have a great day.

Best Regards,
Sandra Hollan

So I decide to check out what BlueBottle offers. Guess what they do? Spam filters. Geez, can’t even trust the guys who are suppose to protect you.
