My ITS recently noticed that some people are using the registration form 
on our patchwork servers to send out confirmation emails to random 
addresses. I was wondering if anyone else had experienced that or had 
implemented some type of protection against this abuse?

 From the looks of the patchwork code, there's nothing built in. 
However, it does look like we might be able to easily add a captcha type 
field to the registration form[1]. Would this be something of interest 
to you guys?
