I am having spammers sign up and activate the blog. I have the terms of service set up and did not have this problem until the last few weeks. Now I get 5-15 new blogs to delete daily from this new threat.
They all have the same look, firstname.lastname@example.org‘s.
There have been a few that come from the same domain. I have not checked for repeated IP addresses.
So this new threat can fill in the right fields on the sign-up page, check the box for TOS and then click on the activate link in the email sent to them, is the way it looks.
Suggestions for defeating this?
