Bill Pytlovany dokumentiert in seinem Blog eine Mail von Spamhaus:
Harvard is trying to protect their users from the tens of thousands of blogspot.com URL’s set up by spammers in just the past month.
We advise all users to consider emails with blogspot.com links in them as probably spam. Your emails include your non-spam blogspot URL. Sadly, on the same IP address is the tens of thousands of spammer URLs.
Until Blogspot (Google) can come up with a solution to the abuse, we’d advise you to use tinyurl.com or easyurl.com to „mask“ your blogspot.com link when included in emails.
