I just got a sign-up to one of my Google Groups from this e-mail address:
--@stpetersdbb.catholic.edu.au (I removed the first part for security reasons.)

Now, it's possible that this could be a student of that school - but do you think it's common for teachers/instructors or anyone managing school website blocking to actually seek out groups that promote fresh proxies in an attempt to block them before they hit the students? I suppose it happens all the time, but I never really entertained the idea of them joining groups for such a purpose.

Your thoughts?
